First thoughts are either a defective tune or vacuum leak. Tend to lean more towards the former and hopefully the email response aides in identifying the culprit.
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
