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!

Sorry, but we haven't tested one.
