Hello fellow diesel fans, I am running an edge evolution tuner and when on my extreme tune it will run like a champ for maybe the first few minutes then it seems to go into a sort of protective mode, tuner has come up with cylinder 1 contribution balance fault then it dissappeared and then cylinder 2 did the same thing, and same story it left then this process repeated with cylinder 6 and now cylinder 7 and it has stayed on cylinder 7 for several weeks, all of this has happened in the course of probably two months. The truck seemingly losing its tune has only happened for about the last week but you can turn the truck off and back on and it runs fine then starts running rough again after a few minutes. Truck has a rough idle and stutters occasionaly but not while running good on the tune, a friend with a cummins that constanly bashes my 6.0 thinks it could be the camshaft position sensor that is a common problem on my 05 stroker, please help im new to the diesel world but would never trade a rough running ford for a pristine cummins

Use your edge to pull the DTC's and post them up. It sounds like your FICM is causing poor performance with your injectors OR you have 4 injectors that are going bad. Either way, that will DEFINITELY cause poor performance.
