I have got a tuning question, i have been fighting a tune for a month now. 

i get good performance but a hard shake in aggressive turning. tried increasing D made it worse, lowered the d and better but not much change really. 

i am on betaflight running rewrite, my P is conservative at 4.4/4.8 d is at 13/16. but my i term is .40 that seems to be the only way i can get it to hold position on forward flight. 

I am not getting bounce back after rolls either. tpa is at 0. is it possible that the i term is the culprit, should i lower i back to .30 then really up the P to try and get it to hold position?

Add some TPA. It is the P values being too high that causes that oscillation during hard turning. TPA should help this.
Too much I will cause it to over compensate in fast turns

No I is for holding.... prop wash is the relationship between P and D.

You are correct. That's the problem. It's trying too hard to hold its position at high speed. The quad will fly fine with the I a little too high until you do a fast turn. Then it starts having problems holding position. It over corrects.

for what is worth, i turned the I back to .30 and upped my P 1.0 on both axis and it felt a lot better, it was holding position fine. but the video came out worse. gonna drop the I some more to .25 and try again tomorrow.
