I have a weird as thing going on with my vlt. it will drive perfect but will not idle. Sometimes it will idle good other times it wont, lots of black smoke comes out the zorst when accelerate more than usual. I have checked the fuel pumps, injectros, afm, co2, no air leaks ran it on the dyno at work today perfect only runs 9psi. its a daily driver until i get the big motor done for her. any input will be awsome

The smoke might be you turbo seal. The runing ruff might be your CAS.

yeah I thought about that, but the smoke is not blue its black like running rich.

When the turbo seals went in the T3 high flow I was pouring out black smoke under boost. If it's under load & smoking it would have to be the seals. If it was idling & blue smoke is coming out it would usually mean it's running rich. I don't know, I'm just speculating.
