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?

THERE IS NOTHING THAT WILL INCREASE THE MPG On A 6.0 gm
Slow down,
And......
Reduce weight!
The previous owner never reset the trip odometer or the MPG calculator.
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 ...
