20a1p and eeprom reseting

On a brand new 20a1p, slow burns after a bad mcc 03rg20 burn.
Did a reset of learnt media using eeprom utility , and the issue seems to be resolved.
Do I need to reset hypertuning too?
(the only media this drive burned are mcc 03rg20, some plasmon cdr which burned very fast and verbatim dvd-rw x4, so no unknown media)
