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?

Don,
He mostly drove the Chicago area tollways and expressways where traffic moves at 70 MPH (speed limit is 55 MPH).
My 6.0L gets 18mpg at 70-75mph, not 7.1. Even towing my TT at 70mph gets 8mpg which is due to the huge frontal area, not the weight.
I can't believe 7.1mpg for any real world driving. Maybe lots of idling? Maybe he forgot or didn't realize the trip computer was reset? Maybe another person test driving it got 7.1mpg?
Anyway, if there was an inexpensive way to reliably decrease the amount of fuel consumed, the OEM would do it. They have the most to gain, not consumers.
If you want only want to use 87 octane, don't bother. IF you are willing to pay for premium fuel, check out Black Bear, but I think most of the SOTP feel is trans shifting not engine tuning. Take that $100-2500 and buy fuel gift cards. :)
