I too am getting over 18.5MPG on my 07 5.9 QC dually. I still cant believe it. And yes this is hand calc. this is a great improvment over my 2005 Superduty that I just traded in. What a good move switching to the cummins for sure

Advocate of getting the ban button used on him...
If you see a blue Mega Cab it's me!! I have the Quad mileage module and keep it about 65mph and so far have still been getting 20.5 -21.5 mpg. hand calculated.

I moved from Texas a year and half ago and if your getting 20MPG down there you're doing good.. I mean they only have three seasons... Winter, Summer and Super Summer..
