My lift goes on this week with 37's and I predict that my lifted 6.0 with the same size tires will out shine in mpg. Not too happy with the 6.7's mpg but everything else is all smiles.
I dont think the computer takes into account how many gallons of fuel is being sprayed into the DPF during a regen, thats about all I can think of.
