Really basic stuff. Maybe he is reading it wrong or maybe he didn’t scale the limits of the sensor correct. The 3bar map sensor can read 3bar absolute, so up to 2bar of boost or 29.4psi of boost, so even then, why the code? Seems like he needs to fix something on the limits or something that is causing the error/DTC.
Based on your peak mass airflow of 210 g/s, you are also not at 22 psi.

"I've tuned 100+ of these map sensors, its definitely not the scaling. I actually took a map from a car I just did that has the same setup as you. Your car still did the same thing.... so something is going on"
Is what he said. He seemed pretty sure it was not, in fact, the scaling. I get what you're saying though and it seems like that might be it. Maybe I just need to bite the bullet and get CSG or somebody to take a look at it
