Thread: Riva Stg 2 upgrades
05-29-2007, 02:22 PM #1
I have a 04 RXP w/ Riva's full stage 2, RE blockoffs, Riva sponsons, GH skegs, rr motor mount, Riva stainless wear ring, Riva tstat, wedge, ext rod, filled ride plate holes and probably a few other things I am forgetting, best speed to date was last August in 92 degree heat, 75.6 @ 7850 rpms with a untouched 15/20r......what kind of gains could I expect with the new Riva ecu, injectors and the gh green supercharger impeller?

I also have a RR ecu that is on my gtxsc, had planned on swapping ecu's and throttle bodies but have not had the time to mess with it. How do I tell whether the rr ecu is the the stock class or race version?

Well looks like I am going pass on the Riva ecu special since nobody here has any input.......this board used to be really informative and helpful...

It all depends if speed is worth giving up any waranty?
That is something that you have to factor in.

Warranty is not a factor since my RXP is a 2004, just trying to get the most speed for the money.

the riva ecu woud not be worth the money unless you are going to do the rude or the riva s3 s/c
and the riva valvetrain upgrade etc etc
i think it works best at 84-8500 rpm
