Hey guys, I have recently encountered a problem. My car had been protuned and was running really strong for a week and now it just isn't pulling like it was. I know it's not that I got used to the power or anything. I mean it lost a ton of power. It idles and runs fine but when I give it gas, the sti just doesn't wanna go. There isn't any weird sounds or anything.

There isn't a boost leak. I have checked thoroughly.

As far as mods, I have: invidia dp & exhaust, cobb sf intake, 50/50 bov, cobb ap.

Any help or ideas where to look is much appreciated

No CEL's ??

Bet it's a boost leak... I know you already looked but there are a TON of places to look.


When did you notice the power change ? In the middle of a pull or after it sat for the night ?
