my car runs like crap. if you run it to redline in a gear or two it doesnt pull hard at all intill 6000 rpm then it pulls a little. then 2-3 min later check light turns on then 5 min later it shuts off. when iam driving the car and it is warming up it doesnt want to go anywhere but it is boosting. and when i put my free flowing 3 inch side exit exhuast i get mad boost ceep. so now iam running differnt exhuast that is a stock down pipe o2 housing 2 inch exhuast pipe side exit. i still have boost creep but it isnt as bad but the runs worse. i never had this problem last year. i cant scan the computer. i tried to put the scanner said it couldnt read it.
