Hey all, picked up my used camaro about two weeks ago from the dealership and I love it! Question is what did the previous owner do to it? I can see they installed a k&n cold air induction, flowtech exhaust, wing (zl1 wing maybe?) Pulse wheels, but thats about the end of my knowledge of camaros. Is there anyway to tell if they had a tune done? The car runs like a scorched dog and sounds great but all these upgrades and the car only has 11,000 miles after two + years? Any tips, advice, knowledge is greatly appreciated. Mike
