Default chasing knock

2021 FLTRX, SE stage II installed. getting pining, knock retard from 48MAP on up with throttle increase.
Checked compression and got 200psi rear and 205 psi front. Could high compression be the cause of engine spark knock?

Not an M8 owner but from what I undnerstand, that's not high compression for the M8. Probably tune is off.
