Black smoke
OK, took the new truck on it's maiden voyage over the holiday and noticed that even on small hills the truck would throw out a good amount of black smoke(in D with Tow/Haul mode activated).
Shifting it into M and then manually shifting it into the next lowest gear would eliminate most of the smoke, but it was still putting out way more than the 03/04 Dmax in front of me.
My 06 has the following, AFE Pro Dry S Stock replacement filter, and 4" Cat back exhaust. According to the original owner it has never had a performance chip on it.
This is my first DMax, but I have had two Cummins trucks before this one, and normally when you increase air flow = less smoke. Do I need to have the dealer re-flash it to compensate for the increased air flow? What else could be the problem. There are no gages, so I can't see what my boost is, but the turbo sings pretty well with the AFE filter.
CEL has not lit up, so I doubt there are any codes.
Any ideas?
