After fixing a leak in the Pitot tube, ADAHRS unable to settle down. When plane not moving, ADAHRS works fine, but as soon as taxiing, it goes in every direction.
To clear the leak, we put a little pressure in the pitot, up to 160kts.
What are you thoughts? What could cause this? Could my AoA be clogged as well, would it be related.
Thanks again

The Skyview system needs to be put into test mode before artificially pressuring the pitot, otherwise the calibration will become upset. This is explained in the Skyview installation manual. Suggest you contact Dynon support for how to rectify.
From the manual:
When a pitot or static test is performed the sensors in the SV-ADAHRS-200/201 are being
exposed to dynamics that are impossible to achieve in a real aircraft flight environment,
namely, large airspeed changes without the accompanying accelerations and rotations. This
false condition will cause a well-calibrated unit to incorrectly adjust its calibration.
Furthermore, when a unit is in a test situation a change in applied pitot or static pressure will
cause the attitude to pitch up or down. This is expected.
SkyView contains a special mode that allows you to perform required altimeter and/or airspeed
checks without affecting the calibration of the attitude-sensing components.
To enter pitot/static test mode, go to:
SETUP MENU > HARDWARE CALIBRATION > ADAHRS CALIBRATION > PITOT STATIC TEST MODE.
