I don't think your going to see any significant increase in MPG. It certainly will be more powerful (speaking of both the 7.3 and 6.6) but there is no "low hanging fruit" on that tree. It takes energy to make power, and there is only so much improvement that is possible when squirting gas into a cylinder and igniting it. I think we are there. They will make it more powerful and any increase in efficiency that is produced with these engines will be consumed in the increase power rating. That's my take for both Ford and GM new HD gas engines, we will see what happens.
