That was after it had been in re-gen off and on all morning while driving my route. He said sometimes it can take up to 2 hrs. to complete.
DPF Delete and tune would of fixed that problem and netted you at least another 4mpg. I would steer clear of the 6.4 diesel. Mines a disaster. Might look for a clean 7.3 Diesel though.
