7.3L fuel mileage, stock vs lifted

[WLDHRSE]

Hey yall, I'm still undecided on 6.0 vs 7.3 for my next truck. Whatever I get, I'm planning on throwing 6 inches at it right away with 35's. Also planning on a tuner, exhaust and CAI quickly.

So now I'm wondering if you 7.3L guys could tell me what kind of fuel mileage you got on stock tires, and after lifting & big tires? Lift size & tire size would also be helpful. I guess it would also be helpful to know if you have a chip/programmer.

As always, I do appreciate any and all input. I searched on fuel mileage and got nothing helpful.

Thanks,
Cliff

I don't really recall what king of milage I got stock but when I had 8'' life with 37's... on highway driving I could get 18mpg no problem at all... and that was with a 6spd and 4.56's... and yes of course not giving it hell

All I can say is I lost 3 mpg when i went from stock to 6" of lift and 37's. Your mileage WILL drop.

35s in mine 17-20 average

It's going to drop, regearing will help a lot to gain some of it back.

I am getting 14 mpg on a good day not breaking 2 grand while running the TW econ tune. Have the 7.3 sitting on 315s and 4" of lift, 5 inch exhaust, and CAI.

Will any of the tuners/chips help fuel mileage on a 7.3L rolling on 35's? Good or bad, I will probably stay away from DP based on things I've read.

Thanks,
