I have a friend who has a 2010 N55. He just recently took off the Jb4 and went with MHD. He put on Stage 2 because he has the DP for it and stuff. Anyways, he recently got 2 codes:
2C56 - Charging pressure control, plausibility Pressure too high.
2C58 - Charging pressure control: Switch-off as consequence
Here is 3rd gear manual mode

I can't find anything about if the MHD Stage 2 needs the 3.5 bar map sensor, or what is going on. But as I was the one driving it did not feel like he built 20 psi in 900 rpm.
Anything to check that may be the issue?
