So Iíve scaled my maf pretty close with corrections / learning now down to under 3% either way

Iíve got it setup to switch from map to SD at 10psi boost (24.7psia) with 85% blending from 0psi boost (14.7psia)

Logged a second gear pull onto freeway ramp today and the car jumped a little after hitting a slight bump - revs jumped from 7300 to 7645 in next log line, and airflow g/s went from 348g/s to 379.

Can someone help me explain what I perceive to be an inaccurate airflow reading seeing as my maf is scaled?

Or is perhaps my maf scaling out at higher voltage but Iím not seeing it because my final fuel base is changing due to the switch to SD at 10psi boost?

If my last comment / question is confirmed, this would explain the high reading right?

Canít see how a vf37 at 22psi tapering to 18.5 can be making that sort of hp [emoji848]
