6.7 Cummins vs 6.6 Duramax

Well in 2017 at least it would appear that the Duramax managed to out-freight train the Cummins:

When an engine achieves peak on a wheel end dyno is not accurate. A lot of things come into play like how the torque converter locks up and at what gear. Then there is torque management which makes it even harder to depending on the vehicle. Trying to get it just right on certain dynos is down right tricky from one vehicles tot he next.
Wheel end dynos are also done at wide open throttle and the "pull like a train" people are referring to is at low rpm part throttle(normal driving) when the turbo does not come into play as much.
