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?

He got an average of 7.1 MPG for the 38,000 Miles he drove this truck and never towed a trailer.
In the past few months, I have driven it ~4000 Miles.
Without my trailer, I get ~14 MPG.
With my 7700 lb. trailer, I get ~9.5 MPG.
It's mostly how you drive ...
I think I would have had to pass on that. If the average for 38,000 was only 7.1 without any towing, then the previous owner either drove mainly city or beat the crud out of it. Either way that 38,000 miles in reality was X2 or more.
