Stock 2012 Cummins, 4x4, Crew Cab - 20.1 MPG
Here is a sample of the MPG I received after they flashed my computer with the latest EPA patch... I asked them NOT to do this and someone screw up and did it anyways at the dealership. Note, I am getting 12-13 MPG in city. I am having problems uploading my picture thought it shows 20.1 MPG.
