I would log rail pressure and check for boost leaks.

Moved to LB7 section.

Id be checking the intercooler piping right behind the power steering pump for a hole.
Check all clamps on intercooler piping.
Possible that turbo failed, too.

Sounds like boost leak for sure. My lb7 rubbed a hole on the drivers side pipe. Did the same thing.
