Dan:

By having the AOA probe closer to the leading edge, it will be
slightly more sensitive to AOA changes.

By having it 6 degrees above horizontal, it will change the range of
angles that it can detect.

As others have suggested, Dynon can probably give you more specifics
on the operating range of the probe. They probably can't advise you
on what AOA you need to be able to measure for your Legacy.

I would tilt the probe to the correct attitude, but leave it in the convenient
location. Then try it and see. Make sure that after following the calibration
procedure, the results are accurate and repeatable. I cannot recommend
flying a Legacy all the way into a stall, but IF you do, make sure to fly
those test flights with the CG in the forward range, and the necessary
skills for spin recovery.
