What is the optimum RPM range for a stock ECU RXP-X?
I see some people say 8060 and some people say 8180. I'm trying to figure out what is the best RPM to shoot for on the stock ECU'ed RXP-Xs. Anyone have any evidence of what is best on this one? Thanks in advance.

Closer to 8000, the better. Over 8100, timeing starts to become retarded.

This is a big debate. Lots of people say 8000 but some of the best tuners say 8140+. I always saw my best speed with the latter. Only evidence I have for you is that Erik at SpeedFreeks is one of the best in the business and he likes to see the higher number too.
