2006 GTO with M6 manual trans. The best way to describe this is imagine you are jockeying around to get into a parking spot. Alternately giving slight amounts of throttle and then pushing in the clutch. RPM flares up to 1500 to 2000 RPM even though I'm well off the throttle. This is annoying the heck out of me! Looking for some HP Tuner suggestions to get rid of this behavior. I really want it to behave like a carbureted engine in this respect. Car has a mild cam, long tube headers, FAST 102 intake and XAir CAI. I've tuned it pretty well otherwise, it runs great and makes good power except for this annoyance.
