Attention: TDR Forum Junkies 
Here is a different post that I started on it with info.

They have removed both drivelines 1 at a time and driven it to try and rule out any driveline issues. He said it is like a shudder or miss. They have watched the voltage on a snapon scanner for the sensors concentrating on the apps and all reads normal before and after changing the apps,cam,ait and map sensors. They changed them to rule out a voltage change that may have happened faster than the scanner could read. He has $4k into it trying to fix it. My advice is to try and load a smarty to see what happens. But the diesel shop tells him that he doesn't like programmers as he is more comfortable with external add on boxes. He doesn't want to try it. I am telling the truck owner to try mine and see if helps. He is leary though from what the shop told him. He wants to change both computers but I told him to try the smarty first as it will be free and he won't be out anything before he goes down that road.
Are there any other ideas that have been missed?
