    Smoke on the DRD 12v tunes....

    Anybody else runnin a 12v sound tune notice a little smoke from the tailpipe in the lower gears at around 1700 rpm or so while just barely on the throttle?

    I noticed mine doin a bit of that today on my home from work. Ain’t really all the time though...

    Just wonderin if its typical or a bad sign of sumthin else.

    Nope... plenty warmed up by then.

    I know the scenario yer thinkin of though... Does the same thing if ya switch it on too cold. You can hear it in the sound of the engine...

    Then I’ll kick er up a gear and git on it... Smoke goes away and rattle sound comes back in full like everythings hittin like it supposed to be again.

    Could simply be the fuel blend with the lack pilot injection of the 12V tune.

    Could be time to change the fuel filters.

    Probably no cause for concern as long as she runs clean with the 12V turned off.

    12V tuning makes the engine more subject to smoke.

    Got 53K on it... shouldn’t quite be time for fuel filters right yet...

    Seen this mornin my fuel eco dropped a lil bit too, and that bit of puffin this evenin got me skeert. Startin thinkin “oh crap... please not bad injectors already”

    I’ll try and replicate it tomorrow with the tune turned off. Good way to see if you’re puffin is headlights from the car behind ya. That’s how I saw it.


    Good stuff.... Truckers bring it

    Bad injectors don't smooth out or clean up.

    My guess it's nothing significant.

    Yeah.. good point.
    Landin on that “other” Cummins related site after a Google search on it didn’t help my nerves much none either.
