There are also some that I think are a bit confused on how the exhaust brake works. In theory a larger displacement engine like the Cummins should have a higher back pressure psi at the same rpm than a smaller displacement engine like the Duramax and Powerstroke.
You've lost me somewhere. All 3 engines are virtually the same displacement. The Cummins has larger cylinders but fewer, so in theory it should wash, right?
