So I have a 2001 GT, bought it bone stock about a year ago (no check engine
light then). Since then I have done long tubes, bbk catted h pipe, and slp loudmouth cat back, and a mmr cold air intake. I also have a sct tuner but I cannot get the check engine light to go off. Should I just clear it with my tuner or will that fix the problem? The front 2 cats were taken out and the car also has the MIL eliminators. Any help would be appreciated.
