I now have 6900 miles on my truck and is getting much better road milage. 20mph on trip to NC beaches. But I noticed yesterday the engine is running a bit rougher at idle. Accelarating and running high speed the engine is flawless. I had heard at one time after 5000 miles the computer automatically changed its program to full HP and torque.

I posted the same thing a few days ago and got very few replies but the ruff idle went away and the milage dropped back down to normal. I have no clue what happened but it seems to be over it now. I have seen a few people on here make mention of a ruff idle so it must be just anouther 600 quirk. As for the reduced power for the first 5000 miles I dought it. I think its all there from word go.
