Reprogrammed ECU to allow up to 8850 RPMs. R3 upgraded ignition timing safe for all recreational and offshore racing use using 93-95 octane pump gasoline. R3 works great with stock engine components, stock supercharger system, and R&D 14/21 impellor. The R3 program will add snappier throttle response, increased acceleration, and improved top speed performance. The R3 ECU program will also work well with mild (R&D RC1) camshafts kits, R&D Forged Piston Upgrades and mild supercharger pulley upgrades where boost levels will be increased by no more than 2 pounds. The R3 program file does not require a Powershot Fuel Tuner.
