Yes we need to figure out which torque PID is directly related to the airflow model. I don't think we should be concerned about its absolute accuracy, but more its accuracy from run to run. So we need to find out which torque PID the "Air Density Torque Multiplier" plays a factor in. With all the hassle in exporting data to excel in HP Tuners (EFI Live allows you to quickly highlight sections of data and displays average and MIN/MAX values and also tracks the reference cell back to the tune tool) I think this would be the quickest way to gauge performance.
We still won't be able to identify any improvements related to pumping or frictional losses but I would think those are very minimal compared to volumetric efficiency enhancements.
