6.7L Cummins Engine Brake
Does everyone use the engine brake when not towing? I've read mixed opinions on using it 100% while driving. Thanks in advance S Woolery 2012 Aerolite 2014 Ram 2500 4x4 6.7L Cummins

I will add another thing to this. The one thing that scared me into removing my VG turbo and replace it with a non computer controlled fixed geometry was how many Cummins actuators we sell through our dealers. It mostly was due to fried actuator components rather than carbon buildup on the vanes. The computer boards in the actuators would be toast in many of the ones we took apart.
We don't sell nearly as many Powerstroke turbo actuators, but that may change with the 2020 PSD since the turbo on it will have a full electronic controlled actuator versus the oil pressure controlled actuators on the previous 6.7L PSD's. What worries me with that is whether electronic actuators can handle the heat due to the reverse flow design of the Scorpion engine having the turbo placement right in the center of two exhaust manifolds.
The new L5P Duramax is also the first Duramax to have fully electronically controlled actuator, and the VG turbos all the way up to the LML have been oil pressure actuated. So time will tell in the next few years of they will have the same issues.
