So a member here said that the Tech at the dealership told him to help reduce the amount of regenerations the exhaust brake should be run 70% of the time on the 6.7L. So I gave it a try and for the last 357 miles if the truck was running the exhaust brake was on and here's my findings.

I'll be going back to less use of the exhaust brake.
