LT1 MAF Tuning I'm currently working on tuning my 95 LT1, I want to run the MAF primarily with VE tables as backup. I understand that the MAF Hz cannot be changed and that the AFGS value is modified to change the fueling and airflow. After initially changing the AFGS values from stock, do I reference the new modified AFGS values when making changes to the MAF? or do I need to reference back to the stock values. For example, if I change the AFGS value in the cell corresponding to 3280Hz from 11 AFGS so that it's now 12.5 AFGS, and I data logged instances of too much fuel at 12.5 AFGS, would I change the cell that now holds that airflow value, or the cell that originally held that airflow value?

I would also suggest using a Polynomial Regression calculator to smooth your MAF values.
