I am about to get a chip from dp-tuner and was just wondering what kind of fuel mileage you got with the 80 econ setting? right now im gettin around 13.5-14 and thats 1/2 highway, 1/2 city, and with the price of diesel now I need as much as I can get.

 

depends on your foot....but i promice it wont go down..unless your always playing hard..

 

My last trip to ND I got anywhere from around 16.4 to 18.7 depending on wind. And I've always believed my truck got better mpg just under 2k rpm. until that trip and my best mpg came at around 72mph around 2100-2200 rpm (ALL 80econo)

I don't think I've ever got in the 19s

 

Typical results in 1-2 MPG increase (calculated). Trust me, your fuel mileage is going to suffer due to your right foot w/ the DP. It's awesome and worth it.

 

yea I figured once I get it Ill be burning some rubber and some fuel. But I hope I can control myself most of the time and run the 80 econ and save some money, since college kids dont have any.
