I would install a EGT gage before touching that fuel screw.
On days with temps of 85 and above. I can hit EGT temps of 1150 or so with only a light car and trailer behind my truck on small hills. At cruise on flat ground with the same load it is 975. This is with the only fuel pin turned. My pump is all stock fuel setting as far as the fuel screw.
Look at my location also. This is in Indiana. "ALL FLAT GROUND" in my region. Your running in mountains with a heavy load. 2 turns on the fuel screw might cause problems.
Be safe and install the gage then you can dial the truck to your driving and conditions.
