    Are you running a rrfpr? If so, 50s will work in the summer but you may need some 52s for the cold months. I have dialed in a couple Riva ecus with 68-140s and 50lb injectors in the summer without issue.

    I cant answer that without checking A/F. All set-ups are a little different and not all rrfpr's rise the same.

    since you have that controller why dont you use the BIG injectors like JP and HighPSI are using. I think they use 80's.

    We are running Les Cooke reflashed ecus.

    You could run a bigger injector to get fuel pressure at about 60psi at WOT and just take fuel out to get your AFRs right where you want them.

    Its is hard to get the just fuel right with a RRFPR and Rude controller. I know some guys are running a RIVA with RRFPR with 2RUDEs and EX-ET. The 3RUDE is another problem all together. Haven't seen it done, yet.

    What kind of problem are you having with your Rude controller?
