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?

Try to change the ring to 83 mm with 15/20R Solas speed approx 77 MPH

Take some good pictures of the RIVA rideplate and intake grate area. Some else a little weird. Going from 15/22 to 15/20 and gaining 450rpms. Was this all you changed for the rpm gain. I think something is dragging, but I am only guessing. You should be 80+.

Check the bleeder may be bleeding.
You need to have the prop bent to turn at least 8350 for the ecu to work properly. Around 8500 in the morning would be nice.
