I'm curious about the new product: R&D Powershot adj. fuel tuner for those PWC with fuel injection. Does anyone have those, would like to hear your feedback. Riva Crew, can you tell me the difference between R&D Powershot and E.F.I control unit, the pro and con, or are they similar in many ways? I'm new in this forum and had read a lot on this forum and learn a lot in everything about PWC. I heard plenty about E.F.I. unit but not R&D Powershot. Any input would help and I'm sure others is wondering about that too. This is my first time in forum and will hear from me more in future. Thanks!
