It is either in the owners manual or it was my dealer, but the 6.0L PSD motor was not designed for an exhaust brake. This is due to the fact that the seals and other vital components are not designed to handle the "back-pressure" of an exhaust brake.
"Big Rig" trucks are designed to handle this back-pressure and have components and seals that can withstand the pressure.
Thanks,

The Cummins in a Dodge is designed strong enough to handle an exhaust brake.....They just can't put a decent auto behind it to hold it (exhaust brake or not).
Back to the topic, the Dec reflash sounds ridiculous. The engine braking is needed most when you are at cruising speed down a long grade. If you don't have it in the higher gears, what is the point?

The Predator has the ability to save stock flashes to disk and reinstall them later. What would be wrong with borrowing an older uncorrupted flash from some friend?

I believe I remember hearing that it was the variable pitch turbo blades that created an issue with an exhaust brake. The EGR may also have concerns with an engine brake. I read BD's product desciption of their 6.0 exhaust brake and they have an electronic control kit that communicates with the Variable Geometry Turbo and the EGR valve. I would guess that it would tell the turbo to minimize the angle of the blades and close the EGR valve during exhaust braking. Does anyone else know more about this?
