Odd limp mode, E38 supercharged

[GrannySShifting]

Have a centrifugal supercharged car that trips codes and goes into limp ish mode, where you see fuel pulsewidth peeled way back, goes lean etc. Noticed right as hit full throttle baro reading goes from 102 and resets to 90, then it acts a fool shortly after

All the typical P0068 airflow limits are raised, not near MAF 16000 Hz limit, MAF or MAP readings dont suddenly drop out like its a connector issue or sensor? Anyone spot the culprit?

Was thinking the throttle blade moving around but I dont remember ever tossing the P106 and other codes along with that

Earlier run where it didnt do it (but just noticed baro read 104kpa usually 102??)
