Baro sensor is built into the PCM board from memory. There is no dedicated BARO sensor on the truck, eg in the engine bay.
Easy way to check this issue would be take red line off and plug it. Run like that and see.. if that red line isn't connected it cant pull the waste gate and blow off the turbo pressure. If the truck runs fine without it then it's possible the MAP sensor is reading wrong , causing the waste gate to open early.
If the truck still runs the same way you have a boost leak somewhere, which IMO it probably is. Check all the boots and see if they are tight and not split.
Check to see if they lined the turbo up properly too, both sides.

I bet you are another victim of the everscroll, you can turn it of you go to User CP and turn off that option.
