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?

Everyone I have read that has the BlackBear tune loves it. Slightly more power at higher engine speeds only, but far better part throttle performance and feel. There is little to gain for any gas engine tuned for 87 octane. You can get little better for 91/93 octane, obviously with an extra expense.
Skip the cold air intake. An oil and gauze drop in replacement filter that can be cleaned and reused is a good idea IMHO.
My 6.0L took about 20k miles to break in and provided an increase in fuel economy over brand new. Yours should too.
