Somewhere on the forum I posted a lot of info on how the turbo braking works, search under my screen name.

To the guys here who have the Ford 6.7 how is the factory engine brake? It's my understanding that to engage it you need to be in tow/haul and simply depress the brake, perhaps with a bit of force. I have tried to see if I could get it to engage running bobtail and it's hard to tell. I use the one in my work truck all the time (provided conditions are not slippery) and I love it. Part of the reason I went diesel over gas was for the engine brake. BD Diesel has an aftermarket one that does something to the veins in the turbo but I don't want to drop the coin on it if the factory one is satisfactory. Let me know. Thank you
Sounds like RPM's are the key to any of these brakes working. I don't recall the engine speed when I tried mine but I seriously doubt it was anywhere near 3000. Guess I'll have to try the factory one out more on my 2011 before I spend $600 on the BD one. The chart I saw from the BD brake showed no significant braking till about 3000RPM's. Guess I was hoping it was gonna be like my 2005 International work truck where it brakes well at any engine speed. That engine red lines below 3000RPM's though and the brake finally kicks itself off at about 900RPM's. Thanks for all the feedback folks.
First off, your 2011 does not have assisted engine braking or whatever it may be called.
All you have is the inherent engine braking which is minimal due to being a diesel. This is aided somewhat by using the tow haul mode which raises shifts points and lock up the converter sooner and in more gears.
Cummins use to have an exhaust brake, but switched to the turbo assisted braking that is in use by all three now.
First to have it from the factory was GM on the D'max, but that was not until after Banks came out with the the first add on turbo brake upgrade. Ford added the turbo brake on the 2015's. Prior to 2015 the 6.7 had a smaller diameter "single sequential turbine". The design made it susceptible to over-speeding, so no turbo brake option.
The smaller turbine also choked a bit at elevations over 10,000 feet, which by coincidence, is why the Ford-Ram-GM shootouts where always done buy the competition over - 10,000 feet.
It does work well much closer to sea level, which works for me since we live a couple miles from the ocean.
2015 saw the original SST turbo get replaced with a much bigger turbo. Bigger turbo means more airflow and less turbine speed, so we get an effective turbo brake.

BD first announced the brake in 2013. It was supposed to come out in early 2014 IIRC, it was delayed over a year. When it finally came out I got one of the first kits around here. In the instructions there is a disclaimer that the kit may throw engine codes and is not as effective as it could be if the vehicle is still equipped with the EGR system.
I had nothing but problems, the most serious being the truck would go in limp in mode at the most inopportune times. The parts were changed out several times by BD and after multiple conversations with the engineers (including the original design team at an Xtreme Diesel event) I removed the kit.
I sold it to another Ford DRW owner, who also happens to be a site member here. He planned on deleting his truck so wasn't concerned with the giving it a try.
Banks was the first to manipulate the turbo with an add on kit for the D'max, I'm guessing there is a good reason why they did not adapt it to the Ford 6.7
I would say, be comfortable with what you have, or buy a new truck.
