I just posted in another thread, (but I forgot where) that I got about 15.5 mpg on a recent trip to California driving 70-75. Before Bill's tune, I could only get that while driving 55-60.

I think Bill can definitely tweak the fuel usage so that you'll see gains. And, the truck will feel more responsive too. It's a win-win situation.
