car is running like shit

[93talon20g]

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. i never had this problem last year.

Have you checked for shaft play on the turbo?? It is possible your turbo could be just starting to get a little worn out and is not wanting to spool very well. Also, have you checked to see what code is being thrown?? That will give you a lot more information than you can ever get by guessing.
