I've been boosted now for about 500 miles and there's tons of black soot on the back of my car. I was wondering if it were caused by too much fuel or oil consumption.

TIA

 

<--- same problem. its because your running a little to rich. its no big deal, you just have to wash your car a little more often!

 

by the way you dont really have to worry about consumtion unless you have bluish color smoke coming out your exhauset. blue smoke is oil buring. and black smoke is unburned fuel or (running rich). (hense the black soot)

 

Ok that's what I was wanting to hear!!! I'd rather be running rich than running lean!
