my buddy has a 02 duramax all stock they just put changed out injectors all 8 and its smokes a little at idle but when you take of from a lite it will smoke black for 30ft or so them no more smoke . they changed a distubuion block on the back pass side of the head an still the same thing . if any ideas please post thanks glenn
Well it aint gonna go away haha. Diesels blow black smoke... totally normal. You should see mine.... If I were to use my race tune in traffic the road would be so black for 100 yards that traffic would stop lol. Hence why my race tune stays off the street. A little smoke like that is normal for a truck tho.
Get some good clean efi tunes from IdahoRob and it could help to clean it up plus improve your power and MPG
