Do I have to make any adjustments? The system is easy to install and takes approximately one hour to an hour and a half, depending on the persons expertise....Each processor is pre-set in the factory for both water and air injection and is bench-tested to be free of defects. Any tampering to the unit will automatically void the Guarantees other than the air adjustment. The first step for installation is to locate a place for the water tank with a good supporting area away from direct heat such as exhaust manifold. We provide straps with which to stabilize it. Then for mounting the processor: The processor must be mounted slightly higher than the water supply. A bracket is included in the kit to assist you in mounting the processor as close to the point of entry as possible. Six to eight inches from the point of entry is considered ideal. Highly important, make certain that the injection goes in a straight line in! Utilize the PCV vacuum circuit if specified or power booster, if specified only, in the Installation Instructions. It's as simple as "A" to "A" which goes to the vacuum source and "B" to "B" which goes to the water reservoir (refer to the back of the instruction sheet). Then it's time to start the engine and get great fuel mileage and horsepower.
