Mileage is not great but it totally depends what your rear end gear is, what you are doing with the truck and how heavy you are on the pedal. The 6.4 definately does not have the same problem issues as some have had with the 6.0. I have owned both and the 6.4 in my experience gets about 2 miles per gallon less than the 6.0. This is of course due to the stricker emissions.
I am not tuned so I can't speak for the tuned mileage. However, from most of what I have read it seems that they pick up about 2 to 3 miles per gallon but i'm sure the tuned savy will chime in with the facts.
