Don't panic about it, having never flown an IGyro (though I had plenty of experience with other ones) I installed the IGyro in a Habu and had it pretty close after 2 flights and perfect with two more using the software to dial back the axis that was shuddering first till all three were maxed out in both modes without any shuddering at full speed. Then I threw a mix in to bump the gain 5 percent with the wheels down.
