Got an 03 Cobra about two weeks ago that has 2.76 pulley, cat back, Mafia, ported throttle body and open filter. Had a dyno run at Rodeheavers 455/513 but the air fuel was hovering around 12.3-12.5..
Checked the computer and it does not have a chip and no tuner was provided with car. If I get a tuner and have it dynoed again will there be any problems over writing a tune that was put in with I dont know brand tuner.
