Here are is some starting PID’s for the 32bit alexmos board. Its for the same gimbal (eagle eye) but for a 5D camera so might not be ideal for you but should be a good starting point.

Also another thing that I forgot to mention is to make sure that both your IMU’s have the correct orientations setup in the GUI as that can also cause some problems if they are not set correctly.
