Black Smoke
Lately the whether has been fairly good around here, so I took my car out on the free for a joy ride. I notice that when i shift from 3rd - 4th at about 6500rpm. I big cloud a black smoke puffs out from the back firing. Does anyone know how can prevent this from happening again or is it the norm for all SR with 3" exhaust and stright pipe? Running at 10 PSI
