Is there any conversion that can be done to figure out the amount of air flowing into the engine thru the MAF? I know other tuning programs I've used have had a built in conversion. Trying to understand how much air is flowing into the motor versus virtual dyno numbers. I'm thinking I have a boost leak, and need to test for that, but a quick sanity check of airflow versus horsepower readings.

Not that I know of. The HP numbers we have in the drop list are calculated from the adjustment with the load multiplier (K constant) between various models based on what we measured when changing units over on the dyno

Voltage to airflow is on a curve, so it takes more power to reach higher voltages. As far as airflow to load, one would need to graph TP against the power curve on the dyno and see how they correlate. If it was linear, only then could a direct measurement of airflow be made, otherwise some equation would need to be derived
