I just did a little test myself. I have the 250 tune, dpf-delete and AFE intake. I did about a 220 mile interstate trip. I filled up right before and then right after I got back into town. I kept my cruise set at 71 mph the whole time. There were two stops and some slowing and speeding up (especially through Houston). My hand-calc mileage was 18.6 mpg. This was with four passengers, a bed full of luggage, and the AC blasting the whole time. (Man, it was hot today.)

Here in Dallas there aren't too many hills and I mostly do hwy driving and the last tank I filled up I avg 19.7 mpg on a 250 tune. I see on my dash when I drive 65 mph I get 22-23 mpg on the hwy. So I figure that is close to what I make on the hwy since I almost avg 20 mpg even with the little in town driving I do.

Is that hand calc'ed or the lie-o-meter?

The 19.7 is by hand. The others numbers is off the truck. I just figure they are pretty close since I almost avg 20 mpg.

That's impressive. The lie-o-meter on my truck said 29 mpg when I hand calc'ed the 18.6.

I said the samething when I filled it up and figured out the numbers. Before the mods I avg about 16 mpg each fill up. Now almost 20 mpg. I say buying these mods was a good investment. Will probably pay for itself very soon since I avg about 60k miles a year.
