I hav a 98 gp gtp with 3.4 pully a cai, flowmasters and jus added headers and had the converter removed ... could i run a chance of havin this problem? Or does this only happen on 01+ cars? I havent tuned for the headers yet and the check engine lights on bc of the cat i knw and im waitin for the o2 sensor extender wire bc of the headers so im actually not runnin any o2's at all ... I took the car dwn the track and i ran 14.2 @ 97 yea i knw not smart but was jus curious .. By gettin a tune and the o2 plugged back in is there a chance of 13's? my best without the headers was 14.0 @ 96 mph
