What tune are you running? The hotter (bigger) the tune the more mpg

H&s perfomance canned tune . Do you thinks a custom tune can be better ?

It can be. You're running the performance tune correct? Or is it on tow or street

I had worse MPG for at least 2 months after my delete. After I was done testing out the truck's new abilities, my fuel economy improved maybe 1-2 MPG's. It improved even more after installing the in-line speedometer calibrater to compensate for larger tires. I keep my in-dash productivity screen on page 3 of the gauges section now, which practically eliminated all thoughts concerning MPG for me. I hear these trucks break-in some more after 15k miles or so and the fuel economy should improve...

I personally got a 2-3 mpg increase after deleting but that is straight highways runs of 400+ miles... Like Dantron said it could be a matter of break in, driving habits and where your driving that determines what your mileage is going to be. It's the regens that really kills the mileage.

just came back from the ford dealer getting the wife a new vehicle. On the way down i was on street and got 17mpg on the computer and switched to performance on the way home and got 20.7

just an FYI I did some hard data for DP mag before I lifted it. I got 15.2 bone stock, driving 70 , highway only, ccsb 4x4 . after the tune, I got 19.7 (give or take a point but I know it was over 19) with canned HS tunes on performance. as soon as I lifted it, with 3:31's I got crushed back to 15-16 highway on 22/35's and 4.5" lift and smaller 2wd air dam. I get about 12 average in town , even since I went to 3:73's .

Where are you filling up? I gained about 3mpg hand calculated just from switching fuel stations.
