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 perfectly happy with the 10 to 12MPG I get with my Duramax versus the 6 MPG I used to get with my old 7.4L Chevy gasser. But that cost me $60,000.
