I bet this is something that sled pulling fans doubted they'd ever see a few years ago....a Cummins vs a Powerstroke, vs a Duramax, all in the highest class of pulling.
The new Duramax-powered puller was built by Kyle Michaels, and features huge compound turbos, and a common-rail injection system. Considering his competition, and the fact that the truck has just been out a couple of times, we'd say he did very well!
