Diablosport Forums

I have a2006 mega cab 3500 with 5.9 cummings I am on the low preformance setting . I have had this running for awile . But have notice that if I take off hard it pulls great but when goes into 2 nd it falls on its face and aLOT LOT of black smoke rolls out. Btw new extream trans. Was put in about 6000 miles ago. This issue is not seen or notice with everyday driving so not forsure when it started.

fresh fuel filter?

Thanks for reply I forgot about a small trip I took down a allday dry dirt road and cloged my fliter with dirt stuped of me not to think about that but a clean air filter and she fills good. This is not a good start to the forum.

that will do it
