I also asked him if it smoked on decel, he says that he has never noticed it before. Im thinking that the car needs a catch can and a good pre turbo vacuum source. He really has no clue about the car and he got it about 3 wks ago. Im sure it needs a good tune. I mean a car that runs rich will burn black, but if its really really rich, it will come out gray. So considering that the car has 96lb injectors(why?) and a JWT tune, I am sure that it is probably running in the 9's afr at wot. Please chime in.
