I have a intake pulley and tune, and my exhaust tips get a black residue very fast and shows alot more on my corsa chrome tips. Also if its revved up it gives a black smoke. Is this normal? Is this cause its running rich?
Condition normal. My car is white and I get a light black soot on the back of my car. Doing it since day one with several different tunes. Worse now with the off road h and stingers. Even without wot runs.
Yeah what he said. After a couple days of hard runnuing the back of my car has it all over the rear. Looks like someone hit it with a bag of gunpowder. Especially the white stripes
