Use the filter from post #144 here:
https://forum.hptuners.com/showthrea...-airflow/page8
After that it's just like any other type of tuning where you copy-paste special into the tune.
Make sure you're logging Dynamic Airflow, Mass Airflow, Volumetric Efficiency Airflow.
Oh yeah don't fail the MAF or change High RPM Disable. Leave it factory settings. That's the point of the tuning method.
If you want to plot the filter to see its activity then make a user math for it separately. Right click the chart area to add. Select that math parameter you created. Make the min/max limits 0-8.
