Wrong Duramax. This forum is for the 6.6L V8 Turbodiesel that comes in the '01-'13 2500 & 3500HD.
3500 rpm is damn near redline on these motors. lol.

No problem.
Most of us wish that engine was available in the US market. I would love to drive a diesel Colorado.

Many of us here drool over the DMAX available abroad that us here in the states cannot buy courtesy of our EPA and diesels bad image here. Wish I could be of soem help, but there isn't one of them on this continent on the road probably.
