G37Sam

You have to keep in mind, UpRev on it's own won't do anything if there's isn't a brain operating it... All I'm saying is my tuner seemed to know what he's doing, and he did mess with the ignition big time, especially after richening out the mix it allowed him to advance the timing a lot. Now I don't know if my ignition timing was retarded a lot OEM for some reason or if all gulf spec cars are "de-tuned" like that which was why two other G37s saw similar gains but I do know for a fact that it's not just my butt dyno.
