Question for TP/LTH users, oil smoke @ high RPM?

my guess, based on prior cars without cats, is youre seeing the AFR become quickly very pig rich as the throttle closes and revs drop, and some of that fuel igniting late causing some smoke out the exhaust. i had one car that would actually shoot a small flame doing that exact same thing.

pig rich would show black smoke coming out , not blue-ish smoke which is Oil.
but I see what you are saying

There is some black smoke when revving "up". If you watch the video in HD you can see the smoke + heat ripples when the throttle is open.

It is running really rich right now, will be fixing that soon.

The smoke you see poof out after the throttle closes is oil smoke for certain.
