Need some urgent help

[CoastalF350]

My brother has complained to be that his truck has been underboosting and having a hard to accelerating and shifting with no pressure. Its a completely stock 6.0 with a 4in dp and 5in exhaust. Its not deleted nor studded. I got him to read the codes and this is what popped up on the sct livewire ts
Map- barometric pressure correlation
Turbo / super charger underboost
Exhaust pressure sensor
Exhaust pressure sensor high input
Exhaust pressure control valve high input

Any input would be greatly appreciated!

Sounds like he has a EBP sensor issue whether it be a sensor itself, tube or wiring. I have seen the EBP tubes clog up a lot causing these same exact issues I take them off and clean them out with a coat hanger, compressed air and brake clean, and carefully clean the end of the sensor too.
