I have a 06 RXP (stock) with the RIVA Power Filter, RIVA Grate, Solas 14/19, Stock Racing ECU, New Wear Ring and cannot turn more than 7700 RPMs. I have 32 hours on it now and am trying to figure out why it will not turn where it is supposed to. I just put the new ECU on today and it did not make a difference with the RPM's. I checked the oil today and it is where it is supposed to be. Ideas??
