Copter oscillations

Hi
Today after changing propellers from 9545 to 1055 i faced oscillations immediately after applying roll and pitch and it will resume on hover

How much should i reduce/increase PIDs to get stable to run auto tune again ?

Current PIDs :

Config :
Frame DJI F450
FC CUAV Pixhawk 2.4.6
Motors Tmotor 2213 920 kv
Propellers TM1055 CF
Battery GensAce 4s 5500mah
ESCs Emax BlHeli 25A OneShot 125

Those are some high Stabilize Roll/pitch values hosein. Perhaps cut them in half and try it. Or put them on a chan 6 tune pot with the current values at the high end. Rate D looks a bit high too.

thanks @dkemxr
i did this but it seems that PIDs are completely wrong
i decided to detach gimbal and run autotune again

If the gimbal is in place for Autotune it needs to be fixed in place.
