Calibrating my MAF on 2011 3.7v6: JLT intake, ported manifolds, and borla atak exhaust.

Should i be editing my airflow vs voltage or airflow vs period? Ive heard people tell me period table and other say voltage table.

From my histogram data it seems like airflow vs period logs more variance. I can see a lot of movement up and down the period axis while driving. The airflow vs voltage graph shows the car sitting around the bottom 4.5v cell for a lot of time, maybe coming up the axis under WOT pulls.

My gut says use the airflow vs period because it seems more responsive to my pedal inputs, but what do you guys think? Is there a better reason to use the airflow vs voltage for logging my changes to make to fuelling?
