Increase MPG
I have a 2014 GMC Sierra 2500HD with the 6.0 gas burner. I have been looking at computer programmers and air intakes. Has anyone done any of these mods and did it increase your MPG any?

I'm at 10.5 mpg in town driving, 10 pulling a flat trailer and 9 pulling an enclosed cargo trailer (less with wind). Driving 60mph with a 10 mph tail wind this week I managed 14 mph over a tank and a half of gas. Most of the time on the highway it is 12-13.
The trucks computer controls everything. I can drive as gently as possible and it won't make any difference. I may gain a little mileage swapping out to a less aggressive tire, but that is about it. It is all about physics at this point-if GM could get more out of the truck, they would have done it.
