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?

The best way for better mileage is to installed a power programmer and it will show better mileage, might to give it but it will make ya happier.
