smoke under boost

So lately I've been getting a grey/white smoke under boost only in 2nd and 3rd gear early when I first get on it....

It's a short lived smoke but I'm just making sure I'm not going to go boom

Use your nose on this one, what the smoke smells like will tell you what your problem is. If I were a betting man I'd say it's the clutch.

You're catless, and going WOT or near WOT you're not going to be in a perfect fuel ratio so you'll see some extra. If you're concerned get a leak down test performed.

This
A puff of grey/black smoke is normal its just a little extra fuel
If its white/blue/grey and last very long time to start diagnostic sessions

Well I didn't see it a friend of mine who was behind me informed me of it.... the only smell I get is go cart motor smelling due to catless I presume

Disregard my post, I misread the OP, I thought he said he has smoke from under the hood.

U sure it's white? Cause white smoke from coolant is like cloud white. Ur probably paranoid and just seeing the normal smoke between shifts and getting on it. Ur a/f ratio changes at shifts it will go rich for a second, plus other things happening. Temps may be cooler outside than normal which is why u see it. I doubt there is an issue. But make a video of u driving in the conditions u said. Maybe get a second person to record it from outside as u drive by
