Have a few Questions

Yep, goes to show that every truck is different.

The trend is usually better mileage from a tow tune when you have a low axle ratio, bigger tires, lifts and such. There is also a throttle input difference for me as well. My tow tune has a throttle response more lethargic than stock because I had intended to use it for driving off road where I dont want a sensitive pedal. That basically gives me a smarter foot for fuel economy when on the street. It isn't as much fun as my performance tune but I'm not having to visit the gas station as much.
