I was wondering if there is or can be added a jake brake feature on my 2006 F-250 diesel we are towing a 32 ft grand design Imagine camper with a golf cart in the bed of the truck, it stop's fine was just wondering.
Mark, you told me how well the turbo braking worked on the 6.0 back in 2003 when these trucks were all new. I recall that you used an f550 for moving and found the engine braking very effective.It should stay on lower than 40 MPH. As I remember the 4R100 (and it's been a couple of decades) the coast clutch stays on until around 10-13 MPH. Same for the 5R110W.
The 6.0L doesn't have an EBPV. It adjusts the vanes in the turbo to produce the same effect. And it does do that to assist with braking.
