CM2350 Reprogram help

[Carl G]

Hey, I dm you, I’m not very knowledgeable about the Cummins, always been around CAT and Detroit.
I’m running this truck all over the country right now and I carry the laptop with me so whenever you have a minute lmk.

Rn I’m about 77k gross, had a side wind for a few hundred miles.. 4.8mpg at 60mph on 12th gear at 1300rpm if I went to 13th it’d be lower And RAWZE mentioned somewhere bad programming and oil temperature could be correlated?

We’ll always on the red when pulling hills or it’s windy. I actually have the oil cooler waiting for me at home to swap it. But it probably isn’t even the issue.
