Ultra 250 PowerShot Adjustable
Fuel Tuner: The R&D Powershot
fuel injection tuner will deliver increased horsepower, acceleration, and
stronger mid-range performance by delivering a higher performing
Air to Fuel Ratio (A.F.R) to engine. Many of today's high performance fuel
injected four stroke muscle craft have a lean A.F.R. R&D Performance has
tested, documented, and analyzed the O.E.M fuel maps on every current fuel
injected four stroke watercraft, and pre-programmed and coded the new R&D
Powershot fuel injection control module to safely alter the O.E.M. fuel map
to a higher performing and safer A.F.R. (richer). More horsepower, greater
acceleration and stronger mid-range are the result when the proper A.F.R.
is achieved and is tuned for optimum performance.
The R&D Powershot is fully adjustable on the fly (with the engine running,
observed and tuned while riding), and will accommodate a wide range of
adjustability to properly performance tune the A.F.R. for any combination
of aftermarket parts. The R&D Powershot will add horsepower, reliability,
and adjustability to any electronic fuel injected two or four stroke personal
watercraft engine.
