Hills of Kentucky. Mine does it too. I'm curious if a tune would take it out
It might, DeeK. I could see it picking up something like that when it was brand new and still in fast learn. Now, I don't know how long a time/ miles that fast learn stays activated, but being that early in the life of the truck, I could see it learning that if you had a heavy trailer on it and went a long distance. Getting a dealer to reset it to start fresh very well may help you out.

A tune should yes, Pergrem. I mean, back to the fast/ slow learn on the ECM and TCM like I mentioned above; when I tuned my 2004 Duramax from DuramaxTuner, it told me in the directions that after installing the new tunes on the truck, the ECM and TCM would be in a state of fast learn, so you were to drive the truck in each of the 5 tune modes (optimized stock, light tow, heavy tow, sport economy and race and I believe you did NOT turn tow/ haul on during this) at like 2/3 throttle for a couple minutes each to get it used to each one, then you could put it on whatever mode you wanted and drive the vehicle as you normally would.
You might call the tuner you are considering and ask them what they think, but based on that past experience, I would say yes.
