i've got a nice 2001 SD cc dually, 117k. Stock exhaust, "high flow intake", edge prgramer no other mods, so for the most part stock. before the intake i had a decent amount of smoke, on quick take offs and accelerations. (on extreme) after intake i lost darn near all smoke only fast take offs does it smoke. When towing i get a whiteish grey haze when goin up hills and harder accel's. The HPOP is "ok" not strong but no CEL's yet. could that be the smoke, or what? just looking for knowledge. Thanx in advance.
