Just wanted to start a thread so i can see what everyone is getting out of thier 6.7s. People seem to ask it alot. I also want to see if mine is close to others or way off. I did all the deletes, 4in exhaust, afe intake, and H&S mini. Ive hand calculated from 17.9 to 19.8. This is a combination of highway and city with 315/70's.

 

20 give or take a bit

 

So far around 17.5 - 19 but i have only been driving it a week since I deleted everything. Hopefully it improves a little more.

 

16.5 - 17

 

No deletes, 15.5 MPG.

She's not broke in yet either so we'll see if it improves.

mine is 21-23 with stock size tires.

 

hand calculated 20 - 24 highway doing the speed limit nets the better. i lost a little from larger tires.

 

seems like the guys with bigger tires lose a few. also 4.10 gears dont seem to get as good.

 

im running 35s with 6'' lift and i dont do to bad

 

20 with deletes. made 17 without. I'm on stock suspension and tires.
