RIVA CREW: i have your RPM Kit and love it. Great Job, but like everyone i wanna go faster. is the R&D powershot a good add on. it says that you can tune it to match performance upgrades you already have. is this safe and will it compromise realibility?

Anytime you can add fuel typically you add reliability. As for improving performance I can't comment personally. I haven't worked with a Powershot yet. The stock ECU compensates adequately for our RPM Kit so reliability isn't a factor. If you were to modify the engine any further then the Powershot would be a good consideration.

I can make some inquiries or you may call R&D directly if you'd prefer. Let me know.

thanks for your help, im looking to get some top end, w/o forking over the cash to jump up to the endureance kit. any suggestions are more than appreciated.
