    Your P looks too small and I too big.

    I even do not like autotune results. In my practice best results are acquired with I ~= P/3. But it is just my opinion.

    Your log confirms my opinion. It looks like pitch not connected to desired pitch. Same with roll.

    Also you are having EKF_ERR. It means that EKF getting wrong results when new data arrives. I've fixed it with vibration damping. You can give a go too.
