Tuning AltHold climb/fall

Hi all,
I’ve a 7inch copter with a black cube. I’ve tuned my althold like it explained here.
I still have some vibes in pitch and roll pid. But my question is about AltHold, when I go to left my copter climb and if I go to the right he’s go down.

In the abose as you can see altitude often follow roll input. More the roll input is bigger more is climb/fall .Do you have any ideas ?

yes, you need to protect your barometer from wind and prop wash.

Yes but my barometer is inside my Cube no ? I can’t protect more.

Your Cube is not a fully sealed unit so the barometer can take pressure measurements for the AP.
