Help! Bad PCM?

2006 6.0 with 185k. Has no power, tons of black smoke, and sounds like chewbecca when you let off. Have code for EBP sensor high.

Cleaned turbo
Replaced EBP sensor and cleaned tube
Cleaned and checked MAP hose and fitting at intake

Could this really be a bad PCM? Truck ran great 2 days ago. Shut it off to go into gas station for a pop and runs like this now.

A bad PCM would not be the cause of your issue. You have a mechanical failure that will require more troubleshooting to diagnose correctly.
