[/quote]If you have an old P72 (GSR) ecu, and it has a 8200rpm rev limit, then you have some serious issues, and may actually be running the stock program, which isn't wise, as it has pretty much no resemblance to what your car comes with.

I said its not stronger because I know that changing just the ECU doesn't do shit. What's a stock GSR's rev limiter kick in at? I have a bone stock ECU and it doesn't go over 8200rpms. Also I was told by Tony at Jotech it has less agressive fuel curves......is that worng too?
