Did a 1.6 G climbing turn with and the Xtreme AH indication is now sitting 5 degrees low. I have tried a full pawer of restart with no improvement. Any suggestions on recalibration.

Your 1.6G shifted the AHRS mounting. You would have to pull more than 100G in order to have any chance of affecting the accelerometers.

Thanks for reply Rainier, I have sorted it by following the manual and then going to the menu. AHRS reset didn't correct. I then did the next one down attidude levelling. it is still sitting about 5 degrees to the right.

Leveling tells the AHRS to level the horizon to what the AHRS is mounted at - not what your EFIS is mounted at.
Correct the mounting of your AHRS. It is no longer level.
