#1. Why are you driving your car un-tuned? Your next post is gonna be "So I blew my engine." Stop driving until you get tuned. #2. What is your set up?#3. What type of management do you have?

I thought white smoke was oil anyway. Check your oil feed/drain set upYou would be a little safer to run a little rich rather than a little lean.Post back with some details and we can help you figure it out.

White smoke is usually water/coolant. Oil is black and fuel is bluish.

What do you mean your d/p? You dont have exhaust on there?

Does it smoke all the time when you stop or is it only when cold? Also, what is your setup?

vice versa. Running rich is black, from carbon/soot.Burning oil is bluish grey.

to the OP,for the love of god.... PLEASE STAY OUT OF BOOST.

NO tune, factory injectors, factory maf, You don't even have a rising rate FPR to increase the fuel pressure for boost conditions = no idea AT ALL what is happening to the fuel mixture.Not to knock you, but..... there's ALOT more you need to really have a safe/reliable turbo setup.

White smoke is coolant, so i hope nothing happened. Please get bigger injectors, a walbro 255, and a tune as soon as possible.

Sounds like it might have been built up moisture in the exhaust tubing.
