New MPG with aFe stage 2, H&S mini maxx and 4" w/o muffler....after several miles of driving on the HOT setting....just love it!!

[Evil Eye]

23 MPG!!! You SUCK! Congrats... There's no way I can get my truck anywhere NEAR that mpg.

Well, you're getting better mileage in the second picture cause you're driving slower!!!

Just razzin' ya - Got to be impressed with the numbers of a big old rig like this!!

What kind of numbers are you seeing hand calculated cause I've heard the tuners will mess with the trucks computers.

Exactly how I understand it. Once you start changing how much fuel your sending to the motor the computers accuracy for calculating MPGs is shot.

is that truck 2wd or 4wd that the mileage numbers are coming from? Either way though they are very impressive! Congrats!

26.4 by the computer, a little optimistic as the hand calculations work out to a little over 23. This is a 2wd with the only mod being an AFE intake.

i try to tell folks i get 25 to 26 in my 6.0 and they never believe me lol.having a 2wd does have its advantages . I woukd love to have a new 6.7 but till my ole girl bits the bullet i will just stick with it.

65mph @1500rpm. Nice.

Having a tuner in the cases ive seen on the 6.7 hasnt messed up the factory mileage readings. In the few time trips ive taken in one its normally very close within 1mpg generally
