Well I decided to go to the dealer todayand see what is going on with my truck and they were doing more tests. I have to give credit to the mechanic that was working on the truck. He did everything that the tech's were telling him to try. He finally at his witt's end asked them if this was the proper ECM software for my truck. Low and behold, it was the wrong software update. Apparently it was for the f450 if I recall. I will find out tomorrow when i pick up my truck or should I say test drive it first. This might be the same issue that others are having. I will post more tomorrow.
Nothing but a headache right now. Started with contaminated fluid display on dash readout. Changed Nox sensor and module. Next turbo chatter and flutter. New turbo and wastegate changed. Still have turbo and wastegate flutter and dealer can't pin point the problem. 
oesn't have power like other 6.7's. All was repaired under warranty up to this point. Any thoughts from all you 6.7 owner's?
