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?

Drive slower, and highway tires aired way up.
so running a $250 tire at 80 pounds 24/7 is your way of saving money?
There is nothing in the OPs post about saving money. His goal is to increase mpg. Maybe he just wants to drive further between fuel stops.
if that's the only goal then buy a bigger fuel tank.
And how does a bigger tank increase fuel economy? Yes he will get further down the road because he has more available fuel,...but "said mpg," is still "said mpg." I've run chips and programmers in both gas and diesel trucks. Like everyone has said,...I've only seen 1-4 mpg gains, and that's diesel and gas. I've seen my biggest fuel economy gains when I've lowered my speed. I drove my '05 Chevy DRW CC with the Duramax/Allison combo from Phoenix to Dallas back in January. The first tank, I got 15.5 mpg at 80 mph. The second tank, I got 18.6 mpg at 75 mph. I didn't really care after that. Those calculations are hand calculated too, from pump to pump. This truck has a PPE Xcelerator Hot programmer with every kind of bolt on upgrade that you can think of, except a turbo and injectors. I bought the truck new, and never paid attention to the fuel economy. Matter of fact, I paid no attention to it in any of the vehicles that I've owned. My priorities are as followed,...performance first, and fuel economy second. It's all about the speed, and finding the sweet spot for the engine.
