White smoke under hard acceleration

Lifted07Duramax · 06-28-2013, 09:57 PM

could this just be tune related? It only lasts for a quick second and goes away when accelerating hard.
Just normal driving no smoke at all. That or its so light I cant notice it.
No smell of oil or antifreeze

If it's pure white coolant is burning off.

good question, I wanna say any time even after warming up. Mostly because I never floor it unless the oil temp is above 160

I have no cats and muffler delete too if that makes a difference

kind of... if you had a set of cats you wouldn't notice it... a lot of people have had a little smoke like that and tried going back to stock for turbo warranty and they found nothing... if your logs are good and there's no smell or adverse effects and it doesn't get any worse, I wouldn't worry about it.

one thing you could do is go back to a tank of straight 93 and after it re-adapts, see if it's the same or not
