HUGE smoke coming out of my exhuast.
i have 2007 STI with catless turbo back and cobb stage 2. i was toying around with it the other day, slam the gas and the turbo didnt boost as well, when i got of the freeway my car was smoking bad enough to cover the whole road, but only when i gave it gas and it is down on power big time. no engine codes came up. a few people i talk to said it was the turbo and the car does have a history of shooting boost solenoid codes....but i could never figure it out. just want some advice before i drop money on a new turbo.

White smoke could be a bad head gasket, does the smoke have a sweet smell to it? Also a good chance that u rings are tost. The 2007 Sti a very bad engine. I hope everything works out ok for you.
