Default fault codes and limp mode - 05-06-2018, 05:35 PM

I have used the jb4 for almost a year and love it. last week right after starting the car the "drivetrain malfunction, maximum drivetrain output not available" message would appear. i turned off the car and restarted and it was normal.
week later same message now with the check engine light, scanned and found codes
121201 boost pressure sensor, plausibility, caster: pressure too high.
121532 boost pressure ambient pressure comparison boost pressure too high
120408 boost pressure control: shutdown due to reaction

anything i should be looking for? i took the unit out and haven't had an issues since, I'm really missing the power of the jb4 though

When does it happen? After a pull?
