VTT can be altered, too. I believe the AIRMASS tables control shift pressures which can cause behavior along the lines to which it sounds like you're talking.
DRIVE DEMAND tables can, kinda', add to this sort of behavior, but from a different way. Values that are too high can cause shifting such that cause the car to unexpected go out of control. Even s little too much at the wrong time can cause a torque request that's way more than what you're requesting with your foot (pedal). One time I lost control because this table commanded the throttle to stay open, literally, for more than a second, after I lifted off the pedal, and because I was pedaling to keep control, that torque cause me to lose control of the car and I went across 4-lanes of traffic sideways toward a ditch. Too much torque in the wrong part of the map created a correlation to the pedal input that hung the actual throttle open. All that to say: these tables could influence, in smaller part, what it sounds like you might be talking about.
Even adding more in the MAF table can do this.

It is exactly for these reasons I refuse to use the RotoFab Big Gulp intake and the JLT's airflow is SO SILKY SMOOTH in comparison. It makes this scalability so much easier and with such the control of the car and how the torque is applied so when you are flying from having the car weighted racing up the hill to Road Atlanta's turn-11 bridge to being at -Gs floating over the top of hill to charging down the 80-90ft drop in Elevation hangin' onto the last inch of the track... nothing abrupt happens that will upset the car.
We've have tried different throttle bodies on Jeremy's M6 car so we could rule out the transmission doing things on it's own and just looked at the data based on the throttle alone. Once we determined the best path here, we transferred such to my car to see how the transmission would react with both PTM engaged and completely turned off.
