    So I just bought a Hypertech Max energy for my 2010 5.3L and had good improvments in fuel economy (2-3 mpg highway) and HP. My dad just bought a 2011 2500HD with the 6.0L and is wondering if he will see the same level of fuel economy improvement. Anyone out there have any experience with programmers and the 6.0L?

    I put a DiabloSport tuner and I got 1-2 mpg increases. It helped out a lot more with the towing aspect by shifting points.
