Everyone I've talked to that has chipped a truck for more power really likes it but they admit that mpg is the first thing to go once the power is turned up.
Gotta say that it's true. First hand experience too. 180 mile trip there with chip off at 18 mpg. 180 miles back with the chip all the way on, 24 mpg. That was the only difference.
Sure, you lose mileage if you can't keep from slamming the pedal.
