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?

We gain a full 20% in MPG between driving at 55 versus 62.
Everyone who asks about this should add "Oh, by the way, I still want to tow at 70mph."
