Best Fueling box for MPG?

[JFulford]

I’m getting ready to purchase a fueling box for my 2003 and am shooting for the best MPG, without really being concerned with Torque/Horsepower. I’ve got my EGT/boost gauges in place(pre and post) and am in the process of getting an AFE air filter/box. I won’t be upgrading the stock exhaust. Any suggestions/opinions on this? I know most people go for the torque for trailering and such, which we do a little of, but I’d like to a get a few more mpgs across those long flats. Currently, with 2000lbs of trailer and 2000lbs in the bed, I get around 12. 5-13. Empty between 15-18. I currently have an 03 longbed quad cab, 4wd, 3. 73’s, cab level shell, automatic.

Tires

Nope, haven't replaced them yet. They're BF Goodrich

Rugged Trail T/A LT265/70/17, but the tread really doesn't

look that bad, just slightly more open the a standard M+S.

I forgot to mention, I have 16800 miles on the truck.

I got about 2+ better with the EZ on.

those bfgs will last! I got over 51,000 and changed them out with about 20% tread left. Not a bad wearing and riding tire
