Has anyone experienced this problem?

As soon as the car shifts, the throttle goes from ~84% to about 42% for a duration of about 0.4 seconds in the 1-2 shift, then OCCASIONALLY does this for a shorter amount of time in the 2-3 shift.

Overrev RPM set at 6800, shift RPM set at 6400~6500 (I have tried 6000 and 6300 too). This did not occur with the original OEM tune, but as we are increasing the HP/TQ the problems seems to get worse.

The TQ limits in each gear is set to 1000 lb. ft.. The engine is showing about 325ish.

Any assistance that you can offer will be greatly appreciated.
