’02 Nissan Frontier, 3.3L

Hi Nick,
Great to talk to you again. Sorry for procrastinating and not getting back to you sooner regarding the results on my ’02 Nissan Frontier, SE model – 3.3L. Prior to putting the AquaTunePlus on I was averaging around 15.5 mpg. A gas-sucky pig and the hp was nothing to write home to mother about! As soon as I installed the unit, the horsepower gain was actually scary! You might say that it now ran like “a striped ape”. We’re talking about the kind of power that puts you back in your seat. It’s been way too much fun putting “my foot in it”. I knew sooner or later I would have to drive it decently just to get a true reading as to what my mileage increase is. Now, I’m at 22.8 mpg! Oh, by the way, that with towing a trailer. Love it, love it, love it.
Thanks again, J. C., New Mexico

'02 Chev. Impala, 3.8L

Thanks Nick in Tech. Support,
I have definitely gotten the promised 25% increase in my fuel economy on my '02 Chev. Impala, 3.8L. I really want to thank you for your fantastic support in helping me figure out how to install the system. Your rapid phone response and "walking me through" the corrections made this installation of the AquaTunePlusquick and easy.
Best regards, Jerry G., Georgia

'95 Dodge Dakota 3.8L

To the good people at AquaTune,
I finally ordered standard AquaTune for my '95 Dodge Dakota with the 3.8L engine. I was rather reluctant to pay the extra price for the needed spacer plate and you assured me that this spacer plate is absolutely necessary for this application. So, I ordered both items. You also assured me that I would see the results. I'll say! Let me tell you how I use this vehicle...I drive in front of wide load vehicles and am known as a "Caution Spotter" and there is a big warning sign on the top of the truck. Sometimes I average 45 - 55 mph, which just gobbles up the gas fast! At these speeds I would get about 14 mpg. NOW, I'm getting anywhere from 25 - and as high as 28 mpg. Just to let you know what a neat product you have and you can imagine how quickly this system has paid for itself considering I drive hundreds of miles per week. 
I'm glad I listened to your reassuring words, L.S., Michigan

'00 Buick Regal, supercharged 3.8L

Dear AquaTune,
I recently had one of your systems by you on my wife's '00 Buick Regal, supercharged 3.8L. My wife was totally dead against it when I first mentioned it to her, however, I did it anyway as a surprise gift for her. I used the excuse that I was going to do a tune-up on the vehicle while she was at work. She was rather suspicious being I don't normally work on the car. The next day she drove it to work and back and came in the house asking "what did you do to my car? It has never run so good." She also told me she had even burned the tires in taking off from an intersection. Then, and only then, did I tell what I had done and I asked her if she wanted me to take it off. She told me "No way!" Now for the kicker, after approximately one week, we calculated that she went from 28.5 mpg to 38.2 mpg. One and a half weeks after having hers installed, I had you come back out to install one on my '02 Buick Rendezvous, 3.4L at my wife's insistence!!! Hey, who am I to argue. Getting these twoAquaTunePlus kits, is one of the best investments I've made in a long time.
P.S.- The other vehicle is getting a 35% increase in mpg. Yours truly, T.R., Ft. Worth, Texas

'95 Ford Taurus, 3.0L

After reading your ad, I decided to try your AquaTune product for myself. I had the kit installed by my auto tech. on my '95 Ford Taurus, 3.0L engine. To date this systems is meeting and exceeding all my expectations! Thank you, AquaTune, Mrs. Joyce A., Pennsylvania

’02 Ford Explorer E-150 4.2L

Dear Nick,
Just to report back in and let you know what’s happened. Sure glad I upgraded to your ’06 model of the AquaThrustPlus. It sure has paid off. Big Time. I recently drove from Indiana to Connecticut to visit my cousin. I was averaging around 24-25 mpg with the regular AquaThrust. I immediately felt more horsepower than before and my fuel economy was astounding! I went all the way to 36.5 mpg, consistently. I had this van (’02 Ford Explorer E-150 with the 4.2L) for sale and had intended to transfer the unit to my next vehicle once I had sold the Explorer. However, every time I filled up I became more and more excited, to the point where I was actually embarrassing my wife and going to anyone who would listen as they were filling their tanks to tell them about this system. After getting to my cousin’s place, I was sharing with my cousin the results of this system and how it works. My cousin didn’t believe me. Imagine your own flesh and blood not believing you! So, I took him for a ride. Every 81 miles, we would top off the gas tank and we did it 3 consecutive times. Now what do you know, he became a believer. To the point that he bought this van from me, but only after I promised to leave the system on there. Because I did, he paid me $2,000 extra. My wife and I flew back home with more money in our pockets than when we left home. Enclosed find my payment for my next unit which I’m putting on a ’02 Chevy S-10. 
One very happy customer in Indiana, J.S.

’06 Nissan Altima, 2.5L

Dear staff at AquaTune,
I recently purchased your AquaThrustPlus for my ’06 Nissan Altima, with 2.5L. The first thing I have to tell you, this thing “kicks butt”. I live in an area where there are a lot of exotic imports running around who love to show off their ponies. But then, so do I. You are right, this system is just like Nitrous. I came up against a BMW Boxter, I tore ‘em up! He asked me what I had under the hood, but I wouldn’t tell him. I can still overtake even the 6 cylinder jobs. The one thing I am looking for at this time, is a chip that will over-ride the 100 mph governor, which is supposed to be released shortly for my vehicle. My normal, sane driving used to give me 27mpg now, however, I am getting 36mpg.
Also, I want to sincerely thank you. As you remember, I was having difficulty in understanding where the venturi injector nozzle was supposed to be placed. You contacted one of your customers in my area who is very familiar with your systems (many of his friends also have one of our systems) and you arranged to have him come over and give me the needed assistance. I am so grateful to have found this product that increases not only the fuel economy but the horsepower too! Thanks again, L.G., Georgia
PS- I was so happy to have him come over, I took both him and his son out for breakfast afterwards.

96' GMC Jimmy Vortec 4.3L

After hearing about your products from both of my brothers, my husband and I just had to order one. Gas prices are so outrageous here in Alaska that we needed all the help we could get. Well, we sure got it with your AquaTune system. While my brother was here visiting, he, my husband and my son, installed it on our ’96 GMC Jimmy Vortec 4.3L. Prior to installing it the gas mileage was the pits and the exhaust had a real nasty smell. A couple of minutes of idling with the system on, the exhaust smelled clean and crisp, the horsepower went up drastically and, best of all, so did the fuel economy. So far, we are seeing well over the 25%. Sure glad we took their advice, M. H., Alaska

'82 Rolls Royce Silver Spur, 6.75L

Hi Nick,
As you well remember discussing on the phone regarding my '82 Rolls Royce Silver Spur, 6.75L, I was telling that I was having problems with predetonation even when using premium fuel per the manufacturers recommendations. Also I mentioned that the idle was little rough as well as some smoking out the tail pipe, in essence, burning oil. Additionally, my gas mileage was only 9 mpg. Now, after installing the Aquatune ALL the problems I mentioned have been solved! No more predetonation and I am now using regular grade fuel. My mileage increase has gone up 16 mpg even. The smoking it totally gone. Now for the funny part, honestly, I sometimes think that the engine has stopped running when I'm stopped because the engine is running so smoothly now. I have to keep glancing down to make sure that the generator light is on. Horsepower increase is absolutely great. I plan on buying a Bentley here shortly and will be ordering another unit for it.
Thanks for this fantastic product, J.W., New York

’96 Dodge Caravan, 2.4L

Dear Nick,
A friend of mine and I were discussing various gas-saving devices, including yours. So I took the plunge and ordered three of the standard AquaTune units, one for each of my vehicles. (’96 Dodge Caravan, 2.4L - ’88 Dodge Daytona, turbo-charged 2.5L & ’89 Dodge Daytona 2.5L, also turbo-charged). I stated to you that the turbo-chargers have adjustable waste gates and I have them up to 28PSi boost. I also told you that I could adjust this if it was too much for the system. Now, I’m getting back to you on the results…In Hawaii there is a lot of stop and go driving and a lot of traffic. I did NOT have to adjust my turbo-boost, not only that but this system took away all of the turbo lag. I went to the lowest octane rating in the gas I use and on both Daytona’s I am getting 32.7mpg. Phenomenal, huh? Now for the Dodge Caravan…with this vehicle I was getting, at best, 25.7 mpg and now I'm achieving 36.1mpg. Now that I have fully put this system to the test, the friend with whom I was having the discussion is also ordering the system.
Your system is saving me “buccoo” bucks. Your happy customer in Hawaii, G.R.

’05 Chevrolet Avalanche V-8, 5.3L

My wife and I make an annual trip for business and to see relatives. This is an 800 mile trip one way. Before installing the AquaTunePlus system, I had to re-fuel three times to make this trip. Not this year! I re-filled only ONE time; I repeat, only once! I’m so glad my brother recommended your system to me. Also, he was absolutely right, the hp is great and the exhaust has a totally different sound and smell to it. It’s real throaty now and a sweet smell comes out of the exhaust. Your product is awesome, thanks again,
B. L., Alaska (This is an ’05 Chevrolet Avalanche V-8, 5.3L Vortec engine).

’04 Dodge 1500 with the 5.7L Hemi

Dear AquaTune,
I ordered one of your AquaTunePlus units through one of your dealers. I have a ’04 Dodge 1500 with the 5.7L Hemi engine. I also had him install it for me. The first thing I noticed was the increase in hp. Quite impressive! One thing for sure, I have been telling everyone about this system. This unit is saving me at least $23.00 per tankful. Sure glad I bought it what with the price of gas continuing to creep up.
Sincerely, Jeff H., Arizona

’96 Chevrolet S-10, 4.3L

I found out about your product through a friend of mine. He had ordered one a couple of year ago and loves it. My ’96 Chevrolet S-10, 4.3L loves this system. It runs so sweet and my mpg went from 20 mpg, at best, to 28mpg! What I also like about this system is that I can run it in either “race mode” or “economy mode”. Everywhere I go, I’m showing off my system. Makes driving a real blast and now, friends of mine will also be ordering.
Best to you all, J. R., Missouri

’04 F-150 4.6L

Hello Nick and the AquaTune staff,
I am totally jazzed! I bought your AquaTunePlus for my ’04 F-150 4.6L engine. Number 1, I was amazed at how easy it was to install. I took a trip of some distance and the first thing I noticed was that it seemed to take forever to come off the FULL mark. The next thing was that my foot was much higher on the gas pedal and the horsepower’s terrific. Now for the best part, I got a 50% increase in my fuel economy! Not bad, huh?
Now I’m telling anybody that will listen what a fantastic product this is.
My highest regards, A. C. from Minnesota

’04 GMC Denali, 6.0L

Hello folks,
I bought the AquaTunePlus unit for my ’04 GMC Denali, 6.0L after a bunch of guys and I had been talking about it at work. So, I got to be the “guinea pig”. Boy, am I glad I was ‘cause I got every bit of the 25% increase and more. I figure I gained probably 32-35%, depending on my driving. I also bought this unit to help keep my engine clean internally. There’s something else I wasn’t expecting, but I’m sure glad, and that’s the increase in the horsepower. I might also mention, that the system was extremely easy to install. Your support service is excellent and so is your product!
P.S. – My brother says he’s going to be ordering one shortly and I hope his results are as good as mine. L.L., Alaska

’99 Chrysler 300M, 3.5L

Hey Nick & Ursula,
I installed the AquaTunePlus on the ’99 Chrysler 300M, 3.5L. I had been getting around 27mpg, it varied between 26-27mpg. After installing your system, I immediately achieved the 25% increase in the mpg. After tweaking the air adjustment, I went to 37mpg. Just wanted to let you know that I am totally happy with the system. Thanks again for guiding me with the air adjustment. I really appreciate the great tech. support.
Have a great day, D.S. in Utah

’05 Nissan Altima 3.5L

Dear people over at AquaTune:
I recently purchased your AquaTunePlus kit for my ’05 Nissan Altima with the 3.5L V-6 engine. As you remember, I utilized a vacuum tee closest to the throttle body. Going through this point of entry, I received only a couple more miles per gallon. You assured me that if I used the venturi injector nozzle as my point of entry I would achieve all the results that I was looking for. Guess what? I got a whole lot more! I jumped from 24mpg to 32.3mpg. The hp is quite impressive. I also noticed that the intake runners are ice cold. Thanks again for your advice and a phenomenal product.
Sincerely, A.C., Texas

'04 Ford Freestar 4.2L

Dear AquaTune,
Having been satisfied with your product and the 25% increase, for quite a while, I started studying the instruction sheet over again and by simply straightening out the placement of the processor so that the injection would go smooth and straight in and slightly shortening the line, is when my fuel economy really started going up on my '04 Ford Freestar with the 4.2L V-6 OHV engine, I started out getting 14.7-15.1mpg in town driving and 19.3-20.2mpg on the highway. Now, however, I'm getting 20 to 20.7 mpg in town and on the highway 25 to 27.7 mpg at 65-75mph. Remember, too, that I drive with 4 Hankook HPW401 snow tires @ 42PSI, the year around! That is a 35-40% increase in my fuel economy. All this going up a 550 ft. climb in altitude & the hp is quite impressive, as well. Am I happy? Yes, otherwise I wouldn't be writing this. S.L., New York

'91 Toyota 4-Runner 3.0L engine

Hi Nick & Ursala,
Installing an AquaTune on our SUV, a '91 Toyota 4-Runner with the 3.0L engine, was the BEST thing Deb and I ever did.
I was seriously considering getting rid of the bottom heavy slug until I installed the AquaTune!
Installing AquaTune was like somebody cutting everything off the rear. This vehicle felt so much lighter.
I was so impressed I purchased another unit for my '96 Jeep Grand Cherokee, 4.0L engine and my sons '93 Corsica LT with the 2.2L engine!
Thank you all at AquaTune so much for this product. Deb and I are glad to become part of the solution. Thank you, Greg & Debbie, Arizona

'04 Chevy Blazer

Hi Nick & Ursula,
Its been awhile since I met with you last summer and purchased the second Aquatune but I thought I would give you my 2 cents on how its doing. As you recall I traded in my old version of Aquatune which had been on my ' 93 Jimmy which has 230K miles, for the new version and put it on my ' 04 Chevy Blazer. I could feel the difference in power and so could my son. Well this Christmas we took it back "home" to Iowa and as usual we went up I-35 at the pace of about 85 mph (made it to NW Iowa in 12 hours). I had an extra half gallon of distilled water and a bottle of Isopropyl along as well. I found it used less water cruising on the freeway than it does in town. I usually go thru a tank of gas and 2 qts water for 300 miles in town driving. But going 85 mph we made it to Kansas on one tank of gas and averaged just short of 21 mpg. And the Aquatune still had about and inch left in it too. Now EPA estimate for my Blazer says 16 city / 20 mpg highway and they sure don't go 85 on the highway when they test. I usually average about 18.5 in town driving but then my right foot seems to be lead footed a lot! Love that power. And recently I had some warranty work done on the Blazer at the Chevy dealer and when they opened the hood they saw the Aquatune and asked if it really worked. Well you know me, I "schooled" them on it. And every chance I get at the gas pump I'm showing other SUV owners what they can do to get better mpg and power and give them your site web address.

'00 Toyota Tundra, 4.7L

Hello, I ordered your AquaTune water injection system several months ago after 2 of the guys at work installed the system on their truck and car. Was very skeptical, to say the least, whether or not they where running me a line of BS. After an email from you with how to install, very simple, I ordered it for my '00 Toyota Tundra, 4.7L, and received it 2 days later. Installed it that day after work in 20 minutes. Kept thinking to myself this is way to easy. So, to testing. I had kept 9 weeks worth of mpg data before installing. The first day was a noticeable increase in horse power. The first week mpg average was only 1 mpg increase. But, you instructions state that some vehicles take longer for the computer to reset. After about 500 miles, my average mpg jumped by 4 mpg which on my truck that brought it to 18mpg and that is great. Thank you.
Also living in south Houston area, my location went under mandatory evacuation orders during hurricane Rita. I spent 39 hours in my truck in traffic getting to OK . ( which normally takes 8 hours) The temps during the day where in the upper 90s. With the AquaTune system running I used less gas and kept my engine cooler. Thank you. 
Funny story to go along with this. Was at the Toyota dealer last night getting oil changed. Sitting in the waiting room watching TV when 6 of the mechanics came in the waiting area and started asking all kind of questions about the AquaTune system. They where fascinated with it. It got so bad that the service manager apologized to me. 
Thank you ! Michael L.

'96 Ford Explorer 4.0L

Hi guys, Sometime back, I installed this AquaTunePlus unit on my '96 Ford Explorer with the 4.0L engine. I came up to your area for a seminar and dropped by to see you. You noticed that I had installed the wrong venturi injector nozzle. You replaced it with the correct one and made some very minor adjustments and now I am getting 22mpg in town where before I had been getting only 16mpg.Thanks again for your assistance, R.W., Texas

'91 Jeep Wrangler 4.0L

Dear AquaTune,
I've just got to tell you, after ordering two of your standard AquaTune kits, I had one of them installed on my '91 Jeep Wrangler with the 4.0L fuel injected engine. This, as the mechanic says, is a very tired engine ‘cause it has over 200,000 miles on it and I tend to have a “lead foot”. Not only is the hp fantastic, my mileage jumped from 11 – 16mpg with my foot into it. Can't help it, I love the hp increase. Now I'm upgrading my other vehicle to an AquaTunePlus. I will certainly keep you informed on the results. Thanks, D.W., Nevada

'02 Ford Explorer 4.2L

Good morning AquaTune,
Man, I tell you what, this AquaThrust system is unreal!!! Darn near scary! I'm calling you as I'm driving down the highway and this thing is just taking off on it's own. Just goin'. I'm almost on people's tails before I even realize it and am having to put my brakes on. This thing flat puts you back in your seat. Love this system, talk to you later, J.S., Indiana
(This is on an '02 Ford Explorer 4.2L engine)

2000 Ford Focus, 2.0L

Nick, As I suspected, after filling up my tires and finding a nice long, flat 20 mile stretch of highway (from Searchlight, NV to Boulder City, NV), keeping the car at 61 mph with the a/c off I was able to increase my average mpg to 49.7. My wife and I couldn't believe our eyes. The entire 251 mile trip gave me 34.7 mpg, which is great considering the elevation changes I was making 2500 to 3500 to 700 and back. Lots of strain on the little four banger. After 108 miles at 36.1 mpg, I burned 1600ml of water with 71 mph max, 4737 rpm max, and 50 mph avg.
I almost wish I lived back East where there isn't so much mountain climbing. I'd be saving a fortune. I'm having a lot of fun with this test. Thanks again for your help.
Sincerely, Nick D.
(This gentleman was getting 28mpg to begin with on a 2000 Ford Focus, 2.0L Z-tec engine using the AquaTunePlus kit)

'68 Chevelle with the 327

Howdy AquaTune,
I installed this AquaThrust unit on my '68 Chevelle with the 327 engine and I'm running at least 40 more horsepower ( hard to tell), my engine sounds a little quieter, and I'm glad of that, because it was border line illegal with the higher lift cam over 3000 rpm. I picked up 1000 RPM more of a hard pull (5800 to 6800, had to shift, didn't want to break anything). Before, the engine's pull would drop off after 5800 rpm. What I could check for regarding HP was I dropped my, from a roll, 10 to 60 mph from around a little over 4 seconds as opposed from, a dead stop, 0 to 65 in around 3 seconds or a hair over, impressive, everything was happening so fast, even with 3.73 gears. I went from 1st, 2nd at 6800 to 7000 rpm's, to 6th and ZIP, I'm on the freeway. That got the old heart pumping. That's enough horsepower for me, I wanted mileage and looks like I got both. I'm going to check that with a stop watch one time to see exactly what it is, but that is a very close estimate. Gas mileage I don't know yet. I'll check it later, but I'm sure it's better. You can stand behind the car and not smell exhaust as bad as before. In fact, you can't smell much at all. Simple to install. Oh, you are supposed to run medium grade gas, not Premium. It will run better because it burns faster and more complete, also you increase the distributor advance 7 degrees more so you get a longer burn. You believe The engine runs cooler and the engine oil is suppose to run 25 degrees cooler, which I believe. It runs on a Qt bottle of distilled water and 70% alcohol in a 50% - 50% mix. That good for 1 tank full. Should pay for itself with gas mileage increase. Thanks for reminding me about this system Jerry, you gave that push and I'm glad I did it. I thought all you Hot Rodders out there may want to know about an increase of horse power at a reasonable per dollar spent. You're also helping the environment out at the same time for your children. Thanks, I achieved everything you folks promised and a whole lot more. E.D., California

'95 Cadillac Deville 4.9L

Dear gracious people at AquaTune,
This is my second testimonial and I feel that you should know the extra fuel economy and hp I received out of your AquaTunePlus system. I drive a '95 Cadillac Deville with the 4.9L engine. Originally my mileage was 14mpg no matter what I did to improve it. With your standard AquaTune I immediately jumped to 22.9mpg, and I was ecstatic with that increase. However, I took the system off and gave it to my grandson for his Cadillac. The only difference in the two models is the color. I put the AquatunePlus on mine and I am now getting 37mpg on the straightaway! Uphill I am getting 35.2mpg. I also noticed that my transmission is not having to go into overdrive to go up the steep grades. What a fantastic product! The gas savings are phenomenal. Now I am going to order a downstream generator to add to my grandson's car so that he will also have an AquaTunePlus. Thank you again, Frank U., Pennsylvania

2004 Chevy Tahoe 5.3L

I installed the system on my 2004 Chevy Tahoe with the 5.3L engine a few short months ago......WOW! My computer tells me over the last 3 months that my mileage went from 16.8mpg to 20.2 (you do the math). I only run distilled H20 50/50 mixture with Isopropyl alcohol as recommended and with today's fuel prices I am absolutely convinced that if this system works in my big, heavy SUV it will work for any make or model! Thank you Aquatune, and be assured I am spreading the word.

'01 Chev. Tahoe 5.7L

To the AquaTune folks,
End of last month I bought two of your AquaTunePlus kits, one for my '01 Chev. Tahoe with the 5.7L Vortec engine. The other was for my wife's Suburban. This investment was well worth every penny! The first thing I experienced was the sharp increase in hp gains. The next thing I noticed was that I used to get 350 miles per tank of gas now I am getting 417, and that's with my foot into it!! One of these days I will calculate my mileage while driving normally. I will keep you informed and I'm telling everyone I know about this terrific product.
Thanks again, S. H., Arlington, TX

1999 Class A Chev. motor home with 454

Attn: Nick, 
I wanted to tell you the whole story about my experience with your product because it may help others….I have a 35 foot 1999 Class A Chev. motor home with 454 engine, which is not exactly a gas sipper. I've had many other RV's in the past and always enjoyed adding many unique products to them (which I do myself)…..I have a friend who also has an RV and I have always jokingly competed with him regarding what we have installed last. When he called and said he installed your AquaTune system, I was really intrigued. By the way, he also got extremely high results and his RV is two years newer than mine…..So, I called and ordered one of your systems…..All this took place about three weeks before I left on a planned trip of at least six weeks and 6,000 to 7,000 miles….I did find an extra large water container that I've been using…..Well, I finally took off on my trip that lasted over six weeks and we traveled over 6,500 miles. Many of the miles were in mountainous areas….The results were dramatic in power that showed up going over hills and accelerating. I commented many times to my wife that I am going uphill and I'm still in overdrive! It didn't shift down as it did before the system was installed!......Before this trip I had used the RV for three trips of less than 500 miles each. When I called you the end of July, I told you that my mpg had increased from 6mpg to 8.5mpg!...On this trip it varied a little more, but then, I was pulling a full-size Jeep and I also logged 89 hours on my gasoline generator, which draws gasoline from my general fuel tank. So, logging in on this trip at an average of 7.738 mpg and the fantastic performance of the engine were good enough for me!......One more incident that was quite shocking to me was when I had an oil change half-way through the trip. When they pulled the pan with the drained oil out we were all shocked at how black the oil was! I commented that I had this water injection system installed and it was suppose to clean out the engine as well. I believe it, because when I arrived home I checked my oil again and it is still almost as clean as when it was installed….In conclusion, I thank you for the excellent support as well as a great system!! Sincerely, S.B., Camarillo, CA (This testimonial has been condensed from the original)

'98 Ford Super-van 6.8L

Attention Nick at AquaTune,
When I placed my order I told you that if this system would work I would definitely get back to you. Good or bad. Well, let me tell you, I am one happy customer! I put the AquaTune on my '98 Ford Super-van, as you well know, this is a big box van that has the Tritan V-10, 6.8L engine. I was getting 11.5mpg now I am getting a remarkable 21 mpg on the highway! The horsepower gain is absolutely phenomenal. Even the exhaust system sounds completely different. It's amazing what you can find just searching the web. I am so thankful that I found your product. Be assured Nick, I show this system off a lot! Best regards, Michael B., Louisiana

2002 Nissan Altima, 4 cyl

Dear AquaTune,
I installed my AquaTunePlus system on my 2002 Nissan Altima, 4 cyl. on 6/30/05 and left the next morning to visit our twin grandsons in Orange County, Calif. The increase in power was immediately evident – I couldn't wait to check the mileage, so when I got to Barstow, Calif., a total of 159 miles, I filled up to check my mileage. I was previously getting 21 mpg. I got 30mpg driving at 76mph on the cruise control – a whopping 42% increase! I also noticed that my temperature gauge was registering a lower temp. on my return trip to Nevada. As I entered Baker, Calif., called the Gateway to Death Valley – I knew I had to negotiate the Baker Grade – a 17 mile upgrade that starts at about 250 feet above sea level and goes to over 4,000 feet at the top. At the 16 mile warning there is a yellow Caution sign that reads “Turn off A/C for the next 16 miles to avoid overheating”, so I did just the opposite – I set the A/C at max. and the cruise control at 80mph. I passed over 18 cars on the side of the road that had heat related failures. When I crested at the top my temperature had not moved a centimeter! The two words I use to describe the performance are “Awesome & Unbelievable”. Thanks to AquaTune for their excellent assistance with the mechanic installing the system! Sincerely, Don Bond, Las Vegas

'92 Ford Explorer with a 4.0

To Whom It May Concern:
I want to let you know how extremely happy I am that I achieved everything that you promised when I installed my AquaTune system on my '92 Ford Explorer with a 4.0L engine. Not only did I receive my 25% increase in fuel economy, I also received a very impressive horsepower gain. I would also like to tell you that prior to putting this system on, I used to have a serious blow-by problem. So much so that even my valve covers would leak oil from the excessive crank case pressure. This problem has now totally cleared up with this system, and no more leaking oil. I will be recommending your product to my friends. Thank you for such a fine product. Sincerely, Thomas E., Northern California

2000 Ford Taurus 3.0L 

Dear AquaTune,
Just a quick note as to what my results were. I had put the AquaTune system on my 2000 Ford Taurus with a 3.0L DOHC engine and my mileage went from 22 mpg to 29 mpg in town and on the highway to 33.9 mpg. Phenomenal product. Thanks again, SL. New York

'94 Grand Prix SE with 3.1L

Dear sir or madam;
Prior to ordering your product, the AquaTunePlus, I asked you if this system would increase my fuel economy because I was already getting pretty decent mileage at the time. Not only did I prove that it would, my mileage increased by 40% consistently. Your system is absolutely incredible! The horsepower is just as impressive. Also, my transmission doesn't downshift anymore when I go up steep grades. I will be telling everyone I know about this product because I definitely got my moneys worth. Please tell your sales staff thank you for the excellent job. C.I. in Florida

'04 Toyota Scion XB

Hello AquaTune,
I just wanted to let you know how well the AquaTunePlus worked on my '04 Toyota. I have the Scion XB. I use this vehicle mostly in my business and I drive every bit of 22,000 miles in a year. Before I installed the AquaTunePlus on my vehicle, my combined mileage, at best, was 28-29mpg. Now it is 37mpg, that's just a little over a 32% increase! Now for the horsepower, it is awesome for a little 1.5L with an automatic trans.

I also installed a second AquaTunePlus that on my wife's '04 Nissan Quest the other day. This vehicle has the 3.5L engine. My wife loves it! I'll let you know the results on this one shortly. Thanks for a such a great product! C. & B., California

'85 Bronco, 5.8L

Dear AquaTune:
I'm the worst skeptic in the world and a good tester because I leave no stone unturned! Now I know that you're not just perpetrating a fraud. This system definitely works! I got an astounding 18.5 mpg on the run where I was typically getting 11 mpg previously. Let me tell you, my '85 Bronco, 5.8L, 4 valve HO Ford engine with 127K miles on it is running better than ever before. It is smoother, quieter and my sticky valve is stuck no more. Even the rattle in my CAT converter is gone. Can't explain this but, it sure is running smooth and cooler and no more predetonation. I am stoked. I can bury the needle without even flooring the engine. I have power to spare on the top end. It feels like I have a ram air system installed. You keep your foot steady and it just keeps accelerating. My Bronco feels like a mustang on the top end. Even at 85mph, when you step on it, it puts you back in your seat. The installation was fast and though I made a lot of mistakes, Tech support was wonderful. I never felt left alone.
Thank you AquaTune for a wonderful product! Stephen C., Washington

1994 Ford Aspire 1.3L

To Whom It May Concern:
I recently put your AquaTune system on my 1994 Ford Aspire with the 1.3L engine. Just thought I'd let you know that I received every bit of my 25% increase in the fuel economy that you promise and the horsepower is quite impressive. I have been treated excellently by your staff and I definitely believe that I have gotten my monies worth and will be recommending this to my friends. Thank you for such a well-made product and the easy to understand instructions.
Sincerely, Ed Z., Iowa

'99 Pontiac Grand Prix

Attention Nick @ AquaTune:I don't know if you'll remember me, I ordered the AquaTune kit for my '99 Pontiac Grand Prix with an '04 supercharged 3.8L engine. Well, you were right on all points, it definitely exceeded all my expectations! It is every bit comparable to Nitrous without the harm to the engine. I had a friend driving with me to show him the difference and when we hit boost, it flat put us back in the seat, and all he could say was “WOW”! Now for the fuel increase: it went from 32 mpg on the highway to 42mpg. Not bad, huh? Anyway, I'd really be interested in selling this product.Thanks, you have a great product. J.P., ColoradoPS – Before I used Premium fuel and now I'm using only mid-grade fuel and getting these kinds of results.

'04 Subaru

Hello Nick at AquaTune,As you recall I recently purchased a second unit. This time it was the AquaTunePlus kit and installed it on our '04 Subaru. Are you ready for this? The mileage went from 22mpg to 31.5mpg! Be assured I've been telling a lot of folks about this product. From your dedicated customer, B.H., New York

'99 Chev. Suburban 5.7L 

Dear folks at AquaTune,I am one happy camper. I have a big '99 Chev. Suburban with 5.7L Vortec engine. The best I could ever get out of this rig was 15 mpg and that was babying it and not towing anything. Now, I am getting 20+ mpg at 75 mph and that includes towing a trailer. The horsepower will put you back in your seat. I have also noticed that the transmission isn't downshifting anymore going up the steep grades and the engine is running a whole lot cooler. I was so skeptical at first but, now I am a believer. Thanks, A. H. in Wisconsin

'95 Cadillac DeVille

Hello Nick at AquaTune,
Well, you made a believer out of me. I told you I'd kiss my wife if this system would work. And I did! I put your AquaTune system on my 8 cyl. '95 Cadillac DeVille. I love cars that are in good working order. My mileage went from 14 mpg in town to 22.9 mpg. It seems to be getting better and better as I continue driving. I'm so excited about these results that I've told my grandsons about it and they're planning on ordering a system for their cars shortly. Your service and your support is excellent! Frank in PA

'89 Toyota Celica, 1.8L

Dear AquaTune,I started out as a very skeptical customer and I also took the liberty to call your distributor in California to ask him what their overall results were on my kind of vehicle. Because of the favorable report, I decided to order the AquaTune unit for my '89 Toyota Celica, 1.8L engine. I used to burn a tank of gas per week. Going the same distance every single day as before, in other words, driving to work and back, traffic and all. You can imagine my excitement when after a week I was down only ½ tank of gas. I didn't realize that this vehicle could run so smooth. And horsepower – lots of it! Love these results, terrific. Thank you, Hector C., CaliforniaP.S. – I'll be ordering a second unit for my Mazda MVP shortly.

'97 Honda CRV, 2.0L

Hello AquaTune,As you well remember, I first ordered your AquaThrust system for my '97 Honda CRV, 2.0L back in January of 2004 and thought I was getting really good results with it. I then decided to upgrade this system with the Downstream Hydrogen Generator, and all I can say is “Wow”! On my previous engine I was running a turbo-charged application. So I am very familiar with that type of performance. This system far exceeds that, it doesn't damage the engine and, in fact, prolongs the engine life, and gives me fuel economy to boot. Not to mention, the oil temp is down by 25 degrees, just as you said it would be. Nice product, keep up the good work, Pete D., New York

'01 Ford 350 V10

Nick @ AquaTune,I bought one of your AquaTunePlus kits for my '01 Ford 350 with the Tritan V-10. I just want to thank you for all your support. I got more hp than ever, ever expected. Also, for the 28% increase in my fuel economy. I live in a mountainous area and I have noticed that the transmission doesn't downshift anymore going up the very steep inclines! Your company is very professional and helpful and I would like to become a rep. for your product. Your new friend, Kevin G., Arizona

'00 Acura RL 3.5L

Dear AquaTune,Back in January I purchased two of your AquaTunePlus kits with great hopes of improving the fuel economy on my '00 Acura RL 3.5L. As I told you when I was placing this order that my mileage stunk. The average, at best, was only 20mpg. I am very, very happy to report that at last reading, I am now getting 32.5 mpg, and that was with a 30 mph headwind! This product does everything you say and much more! I will be installing the other one on my wife's car as soon as I have the time. What a fantastic product you have. Be assured I'm telling everyone about this.Your very satisfied customer, Tom M., Kansas

'04 Mitsubishi Lancer 2.0L

To our friends at AquaTune,Once again, you've made us very happy campers. I bought a second AquaTunePlus kit for my wife's car, a '04 Mitsubishi Lancer with a 2.0L engine, as a present for her. This wasn't as easy of an installation as my other one but, well worth it! My wife absolutely loves it! She was getting 20mpg overall previously, with not exactly a light foot. Now, driving at 80-85 mph she's getting 32+ mpg and in town 25+ mpg. The horsepower gain is incredible. She's happy and this makes me very happy. Talk about a present that keeps on giving. Thanks again, D. B., Georgia

'90 VW Vanagan Suncro 2.1L

I ordered an AquaTune for my '90 VW Vanagan Suncro with the 2.1L water-cooled engine and had my mechanic install it. Needless to say my mechanic was quite impressed with the results after this installation. When I came to pick up the vehicle he told me I gained every bit of 30% increase in hp. As he puts it, it definitely gave it some big “kahunas”. Of course, after driving it myself, I am in total agreement with him. This is why I am placing my second order today for an AquaTunePlus for my '90 Audi Quatro. Your happy customer in New Jersey, R. D.

'89 GMC 2500

Dear AquaTune,
I have an '89 GMC 2500 converted van with a 350 V-8 engine. Before I installed your unit on this particular van, I was getting 16 mpg at the very best and having predetonation problems, which is why I was using premium fuel! I immediately jumped to over 20 mpg with low-octane fuel. Also, the increase in hp is fantastic. I am very pleased with your product.
R.T., Florida

'89 Chevy Suburban, 5.7L

Hello AquaTune,
I bought your AquaTune system for my '89 Chevy Suburban, 5.7L, 4-wheel drive. This is the 1500 series. With this gas hog I was lucky to get 14 mpg on the highway. Now I am totally beyond myself because on my last trip I got a whopping 28 mpg! You can best believe I've been telling everyone about this product.

'90 Chevy 5.7L

To Whom It May Concern at AquaTune,
Just thought I'd drop you an email about the AquaTune system I installed on my '90 Chevy utility truck. This vehicle has a 5.7L 350 engine in it. At this point, this truck has over 423,000 mile on it. I installed a factory-crate motor on it at 276,500 miles. This gas-sucking monster was averaging only 15 mpg prior to installing the AquaTune system. Now, after driving over 30,000 miles with your system, I am averaging over 24.5 mpg. In my in-town driving it is 19.5 mpg. The truck has definitely more pulling power as I am going on uphill grades and doesn't downshift like it used to. I consider this an incredible increase with your system. Because of my recommendation, friends have ordered from you also.
R.B., Texas

'96 Ford Ranger, 4.0L

Dear AquaTune,I thought I'd include my comments on my registration card. Your system works very well on my '96 Ford Ranger, 4.0L. It definitely has a very feelable increase in torque and smoothness in every gear from 1st to 5th. I'd love to give you my fuel increase but, with the increase in the torque it's just too much fun. My foot's buried in the pedal too much.Thanks again for your fine product,D.S., Nevada

'89 Ford Escort 1.9L 

Dear AquaTune,
It's me, Larry, again. After buying and installing this new product of yours, AquaTunePlus on our '89 Ford Escort with a 1.9L engine, I was absolutely floored at the increase in the fuel economy! Not to mention the increase in the horsepower. Previously, this vehicle had an AquaTune unit on it. With this system it takes everything NOT to spin the tires. I think my wife thinks I'm doing this on purpose. The fuel economy went from 20 mpg to an astounding 37mpg!
Please note, I just bought a 2004 Ford Focus (with 16 valve ram induction and all the goodies) that is designed to get the best of fuel economy and thisAquaTunePlus is outperforming the Focus, not only in fuel economy but, also horsepower.

Thank you very much. I am so happy with these results I'm thinking of calling the news media, if that's all right with you.

1988 Jeep Cherokee

Hello AquaTune,
I have a 1988 Jeep Cherokee with 260,000 miles. Most of my driving is city driving, a lot of starting and stopping. As with any car that old and that many miles on it, I was having trouble getting it to pass inspection. It had also become very sluggish over the years and didn't have the pickup and horsepower it once had.

A friend told me about a product called AquaTune. Iasked him if they had a website where I could learn more about it. He said the website After researching it thoroughly, I called the distributor closest to me and met with him. HestatedANDconvinced me that the AquaTuneunit could improve the performanceAND gas mileage of my '88 model Jeep.

I have had the unit on my Jeep fora little over twomonths. I amVERY pleased with it. My horsepower has increasedtremendously (it has pickup like it had when I first bought it),AND my gas mileage went from 12.5 to the last time I checked it 17.8. Almost 18 miles per gallon, city driving in the TEXAS summerWITH the air conditioner running. (Amazing)

I wholeheartedly endorse the AquaTune unit. I thank my friend every time I see him for introducing me to AquaTune."I may get another 260,000 miles out of my Jeep"!!!

1992 SAAB 9000

Dear AquaTune folks,
I had Nick install an AquaTune unit in March of 2004. I am a sales rep. and travel 50-60,000 miles per year. I've driven my 1992 SAAB 9000 Turbo 30-40,000 miles with this unit on it. The power is unbelievable and this 2.3L turbo runs like a supercharged V-8. The fuel economy went from 25-26 mpg to 29-30 mpg on regular unleaded gasoline. By now I have a total of 250,000 miles on this engine and it runs as good now as when I first bought it. I highly recommend this fine system. Consequently I've chosen to become an Authorized Sales Rep. on behalf of AquaTune.

1974 R90/6 BMW motorcycle

Hello AquaTune,
I don't know why I waited over a year after receiving your e-mail indicating your Aqua-Tune would work on my R90/6!

I installed the Aqua-Thrust kit late June '04 and what a pleasure to ride now! I maintain a log of all my fuel use - before Aqua-Thrust I averaged 44mpg including riding 2-up, pulling a trailer and having to gear-down on steeper grades. Now it's a WHOLE DIFFERENT experience! My wife and I recently went on a two week trip to Vermont, New Hampshire & Maine, riding 2-up witha UNI-GO trailer- over 2K (2,000) miles and the power & mileage are GREAT! – and no more downshifting - I was able to increase my speed going uphill without sneaking another gear! And, no more pre-detonation! Mileage is averaging 50 to 52mpg & the BEEMER (BMW) has never run 'sweeter' - I 'sync'd' the carbs with a Twin-Max before installing your product but, now it runs even smoother. I highly recommend Aqua-Thrust to any other 'airhead'riders out there - very easy to install - and start having some fun pulling those hills without shifting so much plusa much smoother running 'boxer'! Give it a try - I believe you'll be wondering why you didn't "hook-up' to Aqua -Thrust long before!

Clean burn!!

Hello AquaTune,
I own an automotive repair center. Recently we had a customer whose vehicle would not pass emissions because it was smoking so severely that the emissions testing center would not even insert the probe into the tail-pipe. After installing an AquaTune unit on it, and allowing it to run for 45 minutes, all smoking came to an end. The vehicle was then taken back to the same testing facility and, in fact, the same people and they were absolutely astounded at the difference. The vehicle passed below standards and totally proved my skepticism wrong! I was also amazed at how it cleaned up the rings. I now plan on using this device to take to other shops and dismantling yards that sell used engines. Thanks for both myself and my customer,

'97 Grand Marquis

Dallas, Texas
Hi, just to let you know I feel I'm very fortunate, that is “blessed”, to have called you and bought your water injection system for my car!
My '97 Grand Marquis is now getting the gas mileage of a Taurus. Namely, 26-28 mpg and this at 75 mph on the expressway, and 21 mpg in the city. This, after having gotten 17, at best, on the expressway and 14 in town and the increase in hp is phenomenal!
Needless to say, I'm very satisfied!!! As you know, I now have three (3) AquaTune injection systems. Need I say more? You can rest assured, I'm telling everyone I know about your product!!!
My sincere thanks,
Larry N., Michigan

1995 GMC Jimmy 4.3 Vortec 

Dear people at AquaTune,
I purchased one of your kits after a friend of mine recommended your product to me. He has two of them. I told you I would send you the results from using your product. I have a 1995 GMC Jimmy with a 4.3 Vortec engine that is lifted 7 inches over stock with 33x12.5 tires. I was getting 7-8 mpg. Since installing your system, I am now getting 14 mpg and can notice a big difference in the power! I am keeping up from the start with full size Yukon's. I am very impressed with this system and have and will continue to advise anybody to try this system and you will be impressed too. Once again, thank you for a product that really does what it claims.
Sincerely Yours,
“ Dale” B., Georgia

3.2 L V-6 1993 Isuzu Trooper

Dear AquaTune,
These are my results on using AquaTune on my vehicle. This is a 3.2 L V-6 1993 Isuzu Trooper. It weighs in around 5000 pounds, has 4-wheel drive with mud and snow tires, automatic. The final drive ratio is 4:57-1. Not the greatest truck in town. I use my truck in my janitorial business.
Before AquaTune, I would only get around 15.5 mpg highway driving. Now it's at an astounding almost 21mpg! Around town I was getting 12-13 mpg and now it averages around 16 mpg. With the unit set up for power, I was able to break both rear tires loose for the first time! It was quite a surprise. Before AquaTune, acceleration was lack-luster, at best. Now it is responding and moves when you want to. I now have no trouble merging with traffic! The seat-of-the-pants feel is great!!

1990 Corvette, 5L IROC engine

Hi AquaTune!
An odd thing happened last night/this morning: Last night I was driving the Corvette and I thought that I must have been getting used to the injection system, as it just didn't seem to have the same “poop” as before. So, this morning, I decided to check the system and see how the balance was between the two venturi injector nozzles and, dang it if there was no balance at all, worse still, there was no fluid at all going into the hoses. Hmmmm. I checked the reservoir, and yep, she was dry as a bone. Sheesh. Anyway, I mixed up a 50/50 mix of methanol and distilled water and went sailing on down the road – hey, my power was back! The difference between having the system on and being without the system is huuuuuge – the car just has a whole lot more torque. There seems to be a big difference, it feels way better than an 18% increase in hp.
A tank of gas sure lasts a LOT longer than before, and with all of the added power. I have to admit that I do have “my foot in it” a bit more!
Thanks for all of your help, and I really am thrilled with the injection system!

1979 Datsun 280Z

To Nick @ AquaTune,
I have tried everything I could think of in order to pass the emissions test, including installing new, after-market injectors, which brought my CO up way past acceptable rates at idle, and hydrocarbons were out of sight, both at mid-range and under load. The next step was to replace the CAT converter and EGR valve. Then I heard about the AquaTune system from one of your dealers, Todd Gossling, and decided to install it on my 1979 Datsun 280Z. This was better than spending one thousand dollars.
I just want to report to let you know that it did go through the emissions very nicely with the AquaTune unit on there. I did not have to install the CAT converter or an EGR or anything else. It went through at 1/2% of CO and a couple hundred hydrocarbons at idle. Then 3/4% of CO and a couple of hundred hydrocarbons while under load.
So, it worked very well. The car does seem to run better and I'm very satisfied and just wanted to let you know the results on that and there you go. Appreciate all your help and excellent product.

2000 Mitsubishi Montero

Dear AquaTune,
Just a lengthy note and test results in how delighted I am with your product. Last year I put o ne of your units on my wife's 2000 Mitsubishi Montero and went from 16 mpg to 23 mpg highway miles. I was so happy with the results that I purchased a second unit for my 2003 Honda Element EX with 4-wheel drive with roof racks. I also have a trailer hitch and sometimes tow a trailer. This vehicle has an automatic transmission. The best that I have ever gotten, without the A/C on, at 65 mph, was 21 mpg. Here are the results, the best and the worst, since putting this unit on and having driven over 7,000 miles:
55 mph w/o A/C: Best - 35.5 mpg, Worst - 32.5 mpg, Average - 33 mpg
60 mph w/o A/C: Best - 33 mpg, Worst - 30 mpg, Average - 32 mpg
65 mph w/o A/C: Best - 32 mpg, Worst - 28.5 mpg, Average - 30 mpg
70 mph w/o A/C: Best - 30 mpg, Worst - 26 mpg, Average - 28.4 mpg
75 mph w/o A/C: Best - 26 mpg, Worst - 24 mpg, Average - 25 mpg
With the A/C on, the results were equally impressive:
55 mph - 33 mpg
60 mph - 30 mpg, for over 600 miles!
65 mph - I went to Yosemite over the Grapevine (mountainous road), did 981 miles and averaged 28.2 mpg
70 mp h - 26 mpg
75 mph - I got 24 mpg, going to Joshua Tree, CA and back
All these mileages tested out with the A/C on. These numbers are amazing!!! This is almost a 50% INCREASE OVER STOCK. I love it! The car is peppier and gets great mileage. What more could I want.
Thank you so much.

MGB Roadster

Dear Nick @ AquaTune,
I promised that I would get back to you with the results on my MGB Roadster as to results while racing on the club run to France. This is a grueling run throughout the UK. A leaking fuel pressure regulator in the engine bay ruined my records for the first part of the trip. Fuel was being pumped out all over the place. This was some 400 miles into the trip. I started the figures again, and extended the test to include two long journeys with a good mix of driving conditions. In France, the test included stop-start, short journey s, hard driving and inclines. On the route back to the UK and from the south coast back to Wales, the driving was sustained high speeds and in the last hour over mountainous and country roads. The subsequent return trip to the Midlands to extend the test was again sustained speeds and mountainous terrain.
I was astonished at the increased pulling ability of the engine when the AquaTune unit was fitted. I have had so much fun with it using it on the performance setting that I haven't bothered with the economy setting. So the figures I quote perhaps could be improved, but who cares? I used straight distilled water for most of the test, but found that as you recommend, significant extra power can be obtained by adding Propanol. The mpg figures were not significantly affected either way with this 50% mix. The benefit to the hilly and mountainous driving is quite astounding. The car happily pulled up 10% inclines in fourth gear or third when bends are to be negotiated. Overdrive was not in of course, but the flexibility at all speeds was remarkable. Willingness and pulling power was noticeable and I may have a rolling road test one day. The car already has mild tuning with race-angled seats and valves, (hardened for unleaded use), polished inlet ports and stainless steel performance manifold and exhaust system. Electronic ignition is also fitted.
I have tested the car's fuel efficiency over many years before the AquaTune unit was fitted, and when tuned properly it returned 27 mpg. Over 1,477.3 miles under the conditions described the roadster returned 33.87mpg, an improvement of 25.43%, which is very impressive for older technology.
There is much interest by all who have seen it.
I joked not when I offered to be an agent for you in the UK, or Spain, (we are buying a second property over there), I believe in the product, and I have the market connections in classic car world.
I am well impressed and having fun - thank you very much.
Best regards,
Neil K. Perry.

1979 MGB

Hi Nick and Ursula –Well, I told you that if the system worked to my satisfaction that I would provide a testimonial, so here it is.I'm very pleased, in fact extremely pleased, and downright ‘stoked' about the water injection system. My problem was pinging, and no matter what I did, and believe me I tried everything I could find, it seemed to have no effect. I could eliminate the pinging only if I severely retarded the timing but, then the overall performance suffered so badly that I could barely pull away from a stop.I found that for my car, it's a 1979 MGB, it's still best to run premium fuel, and straight distilled water. I know that some people mix the water with alcohol, and I have tried it myself but, for my car, water only has proven to be the best. I have gone to the next hotter plug, and I have found the optimum timing for all the variables. It took a while, lot's of road testing but, now…wow!Before the water injection, about the best I could get before pinging started was only 2700 RPM's…which is insanely low. But, now I can easily get to 3500 out of first, 4500 out of 2nd and, easily to 3500 or 4000 out of third! What a difference.I never track mileage on paper but, my wife and I take certain drives repeatedly, and I have a pretty good ‘feel' for fuel consumption, and I would say that your estimate of 25% increase in fuel economy is accurate. Today, we drove round-trip from Oceanside to Cardiff and used very little gas, probably less than a quarter tank.Nick, I'm very pleased, and I'll happily recommend this system to anyone.Bruce and Nancy P.Oceanside, California

'79 Olds Cutlass

Hello Folks, Just had something I figured you might be interested in hearing. I recently installed an aquatune on my '79 Olds Cutlass with a '73 350 Rocket V-8. The power increase was awesome, part throttle torque hugely increased, and the fuel economy improved (I'm not sure how much yet. . . I've been enjoying the power increase a little too much). Anyways, I think the aquatune saved my motor though. . . I had a massive oil leak coming from under the (aftermarket) intake I put on the engine, so I pulled it off again and 
replaced the gaskets (with help from a friend). In the process of putting it all back together, we somehow forgot to tighten the heater hose down. On the test drive it blew off when I hit WOT and 30mph in 1st gear, covering the windshield in coolant. For some incomprehensible, stupid reason, I didn't bother to check the coolant level and simply re-attached the hose. Shortly afterward, I installed the aquatune. I kept thinking my car was running hot but for some reason didn't think to check the coolant level. Anyways, to make a long story short, I had the "hot" light come on and soon found that the radiator had very little coolant in it. I'm fairly certain that had I not had the combustion-cooling aquatune system on, I would have burned the engine up. But I just put some water in the radiator and went on my way, without a problem since. I'll get back to you as soon as I get some fuel economy numbers.Thanks for a great product,---Sam W., Washington


Hi Nick,
This sysetm works GREAT! I have been running a 50/50 mix with Isopropyl Alcohol because of the cold weather. NO DETONATION. Since I am unable to advance the timing without the chip, I added a lower blower pulley that boosts 5 lbs. over stock which brings it to 14 lbs. total. Thanks for everything,

3.3L '84 Holden Commodore VK

Dear Nick,
I have the unit installed horizontally so that the logo can be read on it. I did several good runs and my fuel economy showed an improvement of approx. 33%. (This is a straight 6, 3.3L '84 Holden Commodore VK which is the same as the GM Vauxhall in the UK)..I will be testing some more and hopefully generate some orders for you. I was a little disturbed that your competitor at hydroboost is spreading his reports about your product as giving no improvement. I have tested his and other products and have gotten very little - at most - 10% gain. His product is a lot of fuss for nothing.
In touch again soon,
Luke, Australia

Ford 302

Dear Ursula,I've just completed all the measurements on my Sunbeam Tiger (Ford 302, with a 4 barrel Holley carburetor), after the installation of the AquaTune system. The resu lts are really great! Horsepower without AquaTune: 269, Horsepower with the AquaTune: 306!Also, there is a big improvement in mileage but, I didn't make exact measurements because I do not care too much in this field.I made the measurements with my portable dyno (Gtech) but, most important, I feel the difference. The strange thing is that the engine goes better and better every day!Many thanks,Pavlos V., Athens, Greece

1970 Datsun 510 2.2L

Hi Nick,Houston, we have lift off!!! Turned on the unit for the first time with a fill-up in Florence. Basically lacking the needed courage, I filled up with Plus (one step back from the Super I'd been running) and headed south down 101. At Winchester Bay there is a long hill south of town and as I started to climb I thought I'd do a "ping check" so, under load in 5th I stepped down and, not only did the ol' gal not rattle herself to death, it accelerated. Not neck breaking but picking up speed. Never would have done any better than hold steady speed before.This is exactly the seat of the pants kind of stuff I'm looking to document with a fairly tired motor (130k+).Thanks, B.P., Oregon(The vehicle in question is a 1970 Datsun 510 2.2L)

Hi Nick and Ursula,Just a quick note to wish you well and to let you know that my gas mileage has increas ed from 9 mpg to 11.5 mpg on my truck, thanks to you. S.R., Salem, OR

96 Dodge Conversion Van 5.2 Liter

Dear Nick and Ursula,My two AquaTune Systems work fantastic. My 96 Dodge Conversion Van 5.2 Liter (318) went from 15.5 to 19.6 at 70 mph, (pushing a lot of wind, not very aerodynamic) without a hint of sparknock, like I had before. The engine really pulls strong and feels like it gained a lot of horsepower. My van has 65,000 miles and my next Dodge was going to have a 360 5.9 liter in it, but honestly, it would not run any better (and I tow over 10,000 lbs. I am a little over the tow rating, I know, by about 4,000 lbs!) So I will stay with the 318 and AquaTune. I also installed AquaTune on our 27 Sea Ray 454 EFI Year 2000, and it really came alive. The mix I like to use is 50% distilled water and 50% rubbing alcohol (91%). Nick and Ursula, you folks really take care of your customers, and thanks for excellent answers to my many quest ions. WHAT A PRODUCT!! Larry Duchane, Bay City, MI

Saab 9000 2 liter turbo

This product is fantastic. Installed on Saab 9000 2 liter turbo. Fuel savings 25-30% but most noticeable is the whopping power gain. I estimate 30%, about the same gain as a turbocharger would. and I haven't advanced the ignition timing yet, the engine seems to run smoother as well. I add about 20% methylated spirits[ethanol]and a dash of 6 vol. [20%] hydrogen peroxide to the water. The peroxide itself gives a few extra KW as I've compared with and without the peroxide. I know peroxide is one type of rocket fuel. Thanks for a great invention. Regards, Rod from Oz. (Australia)

2001 Grand Am 2.4L

Hi Nick, Just wanted you to know we installed the system on a 2001 Grand Am with a 2.4L engine. We started out with 18.9 mpg now we're up to 37 mpg. What an awesome system! We found the customer was ecstatic, to say the least. R.K., San Jose, CA

‘87 Honda

My ‘87 Honda failed 3 smog tests. Even with an oil additive guaranteed to make it pass, it failed. Even with a new catalytic converter, it failed. It got ticketed and then impounded because I couldn't get it registered. The judge wanted me to donate the car to charity. I put an AquaTune unit on, passed the smog test and have a very zippy car now! I am satisfied because I did not want to do engine work OR give it away. It used to get 26 mpg and now gets 45 mpg and goes faster than the speedometer can keep track of. L.K. - California

1983 GMC pickup w/454

Dear AquaTune,We put one of your units on our 1980 Harley-Davidson. It ran so good we wanted before and after dyno reports and found that we had gained 4.5 hp and, in addition, 4.6 foot pounds of torque, also in addition to this, it greatly reduced the emissions. I was so excited with it that I put it on my 1983 GMC pickup w/454 and was amazed to find that I gained 5 more miles per gallon going from 9 mpg (at best) to a consistent 14 mpg, with a phenomenal increase in hp. And even with the lowest grade ga soline, no more pinging. Just a quick note to thank you again. I'm going to put a unit on all my rigs.Sincerely, Tom Norris/Boulder Ridge Masonry

‘93 Chev. Cavalier

Dear Ursula and Nick,I had come to you to have an AquaTune installed on my ‘93 Chev. Cavalier because, as a widow on a fixed income, I needed to stretch my gas budget as much as possible and also I needed assistance in passing the emissions test. After putting on the AquaTune, not only did I pass the emissions but, where I had been getting, at best, only 15-17 mpg overall mileage, now I get 26.2 mpg.Thank you so much!!! PJH, Hillsboro, OR

'68 Ford F100

Dear Nick, I installed your AquaTune system on my '68 Ford F100 pick-up that has a 390 engine and it really enhanced the performance. Under optimum driving conditions I achieved 27.6 mpg and normally had been only at 15 mpg. What a difference. Thank s for all your hard work in developing this invention!Regards, J.W. - South Carolina

August 12, 2001

Nick, Last night I went to the Cowboys game with my son. After the game as we were leaving the parking lot, I decided to "punch" it while pulling onto the freeway. Boy did it take off! 2nd gear usually gives me a solid "chirp" of the tires but, this time it screeched about 3 feet on 2nd gear shift (this is with an automatic)! On top of that, a great improvement in my mileage. K.H., Arlington, TX


The AquaTune Water Injection unit on my motor home increased the mileage approximately 30%. Because of that, my wife has decided to purchase one for her car.Thanks, M. McWhorter, Texas

2000 Winnebago V10

Fantastic!! Nick after you installed the system on my 2000 Winnebago that has the Ford V-10, I filled up the gas tank where it wouldn't take any more. I drove back to Newport, OR, 88 miles, I even had a head wind for about 20 miles, I don't know how much horsepower the engine gained, but it has to be a lot. I filled up again when I got back, it took 6.8 gal's, I tried to get more into the tank, but that is all it would take. I was getting 7.5 before and that was on I-5 cruising at 63 mph, on Hwy. 18 going up hills, having it kick out of overdrive I got 12.9 mpg. Thanks Nick you have really got a winner. Thanks again...Ron R., Newport, OR

1980 Firebird

I installed an AquaTune system on my 1980 Firebird with a 400 motor. Instant power increase and better fuel economy, topping out at 50% better on fuel. Based on these results I decided to become an AquaTune dealer. K.C. Regina, Saskatchewan

1983 Olds Cutlass 5.0

I have a 1983 Olds Cutlass automobile with a 5.0 - 307 cubic inch engine and a 4bbl. carb. I usually get about 23 mpg on the highway at about 60mph. On May 7, 2001 I drove to Danville, VA and got 30.15 mpg. I was using an AquaTune Water Injection System. This is a very good system. It improves your mileage and cleans out your engine by cleaning out carbon deposits. Your engine will last a lot longer. Get in touch with them. Roger W., Greensboro, NC

‘98 Chev. 2500 duelly 454

Thanks AquaTune,I'm what you call a Snowbird. Had this system installed on my ‘98 Chev. 2500 duelly with a 454 engine. And I haul a 5th wheel trailer. I do admit I was very skeptical and I've kept very precise records since buying this vehicle a couple of years ago. I was getting 6.2 mpg pulling the trailer and 7.4 without. After you installed the AquaTune system I'm now at 13.8 without the trailer and 12.2 pulling it. On my way back to Arizona I'm going to make sure I'll tell everyone I see about this. Sincerely, W. Dixon, Arizona

‘89 Chev

Just a quick note to let you know that after you installed the system on my ‘89 Chev. Celebrity my mileage increased from about 19 mpg to 27 mpg. I was more impressed to see the immediate increase in horsepower & smoothness. Thanks a lot, Dean H., Salem, OR P.S. - No more hesitation, either!
8/1/00Dear AquaTune,I did not get the 30% better that you had estimated instead I got 32% better. What a neat system you have. Love it. The horsepower is great. I've been telling all my friends about this. Tom M. Portland, OR

1990 Isuzu pickup

Dear AquaTune,Had your system put on my daughter's 1990 Isuzu pickup. I know I called you to let you know how it went because I was impressed. Here are the figures showing the improvement. Namely, we are now getting an additional 7.2 miles per gallon which comes to about a 39% increase on this vehicle. We also noticed a smoo thness in how the engine runs and the horsepower is tremendous. Thank you again, Robert R., Oregon City, OR

‘92 Chevy Blazer ‘86 BMW

I had the system installed on my ‘86 BMW and got an astounding 38% increase in mileage and a dramatic increase in horsepower which is very evident going up hills. I was so impressed with this system that I had one installed on my ‘92 Chevy Blazer also. Got a very impressive 32% increase in fuel economy on this vehicle. My transmission doesn't down-shift anymore in going over the mountains on my way to the coast. John K., West Linn, Oregon

November 2000

Dear AquaTune,Forgive the quick note but I just had to tell you this system is awesome! Going back home it took 1/4 tank less fuel than it did coming down. Thanks again,
