Hey guys been researching this and i found a few old threads on this rev matching for the 6L80E on down shifts with the tapp shift.
Does anyone know if anyone has done this ?

yes, it ties in deeply with the minimum air flow tables in the ecu. on the tcm side sometimes the closed throttle downshift option works best on throttle mode.
