Should I not be faster with these mods???
Currently running a 05 rxp with the following mods:
Riva ecu, valvetrain and injectors
riva rideplate and intake grate
xs cooler w/ bleeder
riva reduction nozzle w/ 82mm ring
I'm only seeing 7900-8000 rpm and 74mph. Shouldn't this setup get me into the 80s?
I tried the same setup but with a 15/20 and only saw an increase in rpm to 8450 and 1 mph faster?

What air intake you running? Toss on the OEM venturi and see what happens...

I'm running no air intake at the moment. I tried taking out the reduction ring and with nothing in there I didn't see any changes to speed or rpm

I know. The ecu and x charger shouldn't have any problems pushing a 15/22 right?

With those mods... that ski should run 80+ on a bad day

I tried a 15/20 with a little bit on the trailing edge and it brought my rpm up to 8450-8500 and my speed up to 75mph. But there really isn't anything left there for speed
