RF Interference
You are definitely getting some strong RF interference into the AP to affect the azimuth gyro. Try moving your comm antenna wires as was suggested by Geico266. Let me know if you have any further trouble.

An earlier poster had problems....
....while he was in the hangar. It was suggested that RF could be bouncing off walls, roof, etc and to take it outside.

Most folks who see something funny happen on the TT autopilots experience pitch, not heading, problems.
Make sure you use the latest recommendation for coax (RG58 is no longer considered the right choice); run your antenna wire away from other wires if possible; make sure you have good grounds; etc.
If you still experience problems after all of that, you might check out this thread on the TruTrak forum. $20 has provided a solution to RF/AP interference in a few reported cases now.

I ordered that part from Digikey. Thanks for the link. I am going to pull my comm coax out of the bundle and try and separate it from the other wires which is very hard considering the amount of space I have.
I really cant understand why the guy that wired my airplane, which has done many lancairs, bundled all my coax cables along with everything else and still claims he has never had a problem doing it this way.

It does. I've measured the VSWR, as well as, the transmitted and reflected power directly, both inside and out. The difference is quite dramatic.
