I would love to get better mileage also but when I need the power I gladly accept that power costs mileage. The 5.9 was not a perfect piece when it came out I am sure so if your not happy go to the 5.9 but when they get the 6.7 worked out you will be sad.  |
because you lose more MPG from the regen process than was estimated (by my friend who works at Cummins). I wasn't expecting a 25% drop with an engine that's only 12% bigger
I knew it would be less, but I wasn't expecting 15 MPG highway.
And honestly compared to my friends 5.9, I don't believe my 6.7 is that much faster/stronger. You lose a lot of power with the emissions stuff, which is evident with the dyno results.
