Need Some Help

Ok, as long as you know that that the Avg MPG is not very accurate. Also, a 12 mile drive is not going to give even a remotely accurate average.

Is it the RPM jump that you dont like or the jolt when it downshifts?

Sound: Is there a comparable acceleration example? For example, if tuned at 3500 rpm is sounds like stock at 4500 rpm. Or is it that you CAN hear it stock but CAN'T hear it programmed?

Kinda tricky when I'm not sitting there to listen to it.

The jolt. It slams into the lower gear. Hard to believe I'm not grinding something when it happens.

Haha, its so hard to explain noises by text... plus, I sound like an idiot just bringing it up. We'll chalk that one up as me looking into it too much.

Yeah, try softening the shifts by making very gradual changes.

Not all trucks react the same to tuning, that can be seen all over this forum. There are countless threads about other problems people have had.
