Haven't had mine tuned yet, but I just got 14mpg with my 6.0. Problem there is that those numbers are: without TC lockup connected, small leak in one of the fuel lines, small vapor leak into the cab, bad radiator. The upside to that is: even with all of those problems and a larger displacement it still did better than my 350 ever could.

I'm expecting 16-18 once I fix the leaks and get it tuned. It really isn't hard to drive it nice because it has so much power you don't need to step on it to get up to speed. That and 4-corner drums keeps me cautious haha
