You must first determine if the effect is caused by rapid slowing (too much drag thereby quickly decreasing lift) or too much pitch change (or not enough).
Once determined, you can influence the appropriate actions through the flap lift/pitch/drag scalars.
EDIT: Also consider if flap deployment speeds are too fast or correct for the type, and 2) is your flap deployment speed correct or at the low end of the band. It is not unexpected to add throttle for flaps deployment for light aircraft but if deployed at max recommended flap speeds you should have more time to respond.
Ron Friemuth did an FM for the FSD? 310 back in 2003 roughly and we communicated a lot about that one. Not sure if that is still available for comparison.
EDIT2: Downloaded and flew; flap scalars seem to be...
