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?

, if you think about it for 3 seconds, doesn't it make sense that the vehicle manufacturer would set the vehicle up to get the optimal blend of performance and fuel economy?
