Cummins guys

[Badass2000GT]

Most of the cummins on here prefer the 5.9 over the new 6.7. But the new duramax and the new powerstrokes are a beast over the new cummins.

I know a lot of people on here have the Cummins, but how is it honestly in comparison with the Duramax, both 2011 models in the Dodge and the GM. Thanks.
