You're going up a hill with a load at 1100 rpm, and you have no clue why your truck isn't happy? Really?
For pity sake, give that poor truck some rpm to work with. Up a hill with a load, and my truck would be turning at least 2200 rpm.
Gas is cheap right now. Burn some!
This right here exactly. Your engine wants and needs the rpm to get you up the incline, but your computer is hampering it by trying to keep the rpms low to conserve fuel which lugs your engine which actually burns more fuel.
Anticipate that upcoming incline and manually downshift the thing and cruise on up it then upshift.
