Have you gotten any injector codes yet? Do you have some way of monitoring it? These don't appreciate any air in the fuel lines, that can be a big problem.

My truck did the same thing when my number four injector went out.... Seemed to have a little rough idle, when i got to about 55mph after the torque converter locked it would buck like crazy, if i floored it through that part it would work just fine... Its crazy how one bad injector can make these motors run so bad.

I highly suggest getting a "cylinder contribution test" done on your truck, this will tell you if you have a bad injector.

the guy i had work on it ran some test he said the injectors were a little weak but should last for a while but some times you can get in it and it will drive and ride fine and then others it doesn't just have no clue does anyone know someone who specializes in 6.0 powerstrokes

You need a monitor of some sort. Edge CTS, Scangage, or the Bluetooth OBDII port and the applicable app. There's a sticky up top on monitoring the 6.0.

If you can get a monitor on it I'd check FICM volts while running, as well as battery voltage cruising. You can also check for chafed wires, you'd be surprised at how many points these wires can become chafed.
