After the AUTOTUNE the plane flies almost only straight


I have a question.

I star autotune with parameter P = 1 for roll and for Pitch pids.

In autotune pid parameter P gous down to P~0.3 or less

When starting autotune plane reacts aggressively, but doing autotune reacts less and less.
After autotune plane P parameter in PIDs is sow small wen plane flies almost only straight.

What could be wrong in Autotune parameters?

I’ve changed all the parameters I could think of to solve it, but I did not manage to find the solution
