Runaway Desired Airflow

At a certain threshold (don't know what the threshold actually is), my desired airflow runs away from the pedal command, and the throttle body follows along with the request also running away. This is on a Sprintex supercharged 3.6L Pentastar.

This is more noticeable above about 2600rpm, below that it seems to not really hit whatever threshold causes the runaway.

Anyone know what causes this? It makes it a bit hard to drive at higher RPM in boost, as the pedal sort of turns into an on/off switch.

I'm running NN disabled with Sensed MAP enabled, and I'd like to keep both of those settings that way.

Don't know if you have gone through the info in this post but I spent a significant amount of time on my Sprintex S/C 3.6 to get the pedal to feel much more linear:

Its not perfect but its far far better than the supplied Sprintex tune.
