When the new 6.7 Cummins came out in our Dodge trucks, Cummins had a video of how the new fixed vane with a sliding nozzle turbo works in slow motion on the 6.7 engine.
Cummins gave the turbo exhaust braking around 230 hp vs 180 braking hp for my '03 5.9/Jacobs (post turbo) exhaust brake.
The newer gen 6.7 turbo brake may have even more exhaust braking performance.
My '03 truck has 365+ miles on the odo and the Jacobs has work fine with the NV5600 6 speed manual. The Jacobs came with a T handle that mounts on the side of the gear shifter at the top. My hand sits on the shift knob with the first two fingers pulling the EB on...or off.
The truck is 19 years old and I'm still amazed what it can pull easily and gets great mpgs with very little maintenance.
