Default Blown head gasket?

Pretty sure this is an obvious one... but i ran the car at 5psi for a little bit. got back and it just throws white smoke everywhere. like a diesel's black smoke. and there is coolant dripping out of the exhaust....

this car is so frustrating. i didnt over boost at all i never even went to red line. only drove it for half a mile..... i dont get it.

Is it overheating? and have you check if you're getting any bubbles in the radiator? if there's any, rev it some to see if the amount of bubbles get worst.

it ws being tuned by solomon at lt1pcmtuning.com

the only thing was the knock sensor kept retarding the timing. my af was good. it ran good till the knock sensor started retarding the timing.... it does not over heat. it runs fine. its just like a diesel throwing smoke so i dont drive it.

maybe the knock sensors were pulling timing because you were getting knock !!
and detonation has caused the blown head gasket, might want to check piston ringlands as well.
A leakdown check might give a clue to whats up internally.
