My buddy just picked up a new Z06 and has already installed headers, intake, cams and an exhaust. He is calling me out and I need to know if I need C16 to beat him? How can these cars trap 127mph stock with only 500hp? My car has a 74DBB, fuel, HKS 264's, AEM, Full 4" exhaust. Pretty much the same setup as braddman. Do he stand a chance or will I rape him?
