Wow, you should come drive my 2011 6.7L with 4.10s. I can pull out on the highway and put my foot on the floor and this thing moves. Mileage is nothing to brag about. While it won't put me back in my seat like my 08 hemi with 3.92s did, it is impressive.
My TT is 7800 pounds and coming back from the lake last weekend I looked down and was cruising down the road at 85. Mental note--use cruise if not concentrating on speed...

Normal conditions. Ha. Can never seem to get a decent day without much wind so usually empty with cruise on at 72-74 I avg 14.5. Towing I have been getting about 9. Definitely not impressed. I had a 2001 Cummins that I used to get 17-18 mpg and got 13-14 pulling! Can't wait for warranty to be up, will change some things on this 6.7L.
I do only have 7500 miles on it so far and people are telling me it should improve some after 10k+.
