Well. The guy that "tuned" it wont email me crap. Looks like im in the dark here, I'm just hopeing he didnt lock the tune. I can rule out the throttle body by removing my ls3 one from my camaro. Think that would work? I would pay the guy a visit but hes 2 hours out of my way.

The car worked fine till about a month or so ago when the rpm started going up on its own....any other suggestions?

Might just end up getting a proper dyno tune

2009 G8 GT SRM, OBX Catless Long tube headers, DOD Delete, LS3 stock cam, tuned with HPTuners, Atari gauges.
