Would someone be willing to provide final auto pilot set up numbers that you ended up with ?
I have the 307 head
Garmin servos Pitch / roll
 
G3X expert Steve posted numbers the other day, these seem to work very well from my experience.
The only thing I may suggest would be to increase the roll servo torque a bit (I use 30%).

These settings should be a good starting point.

Thanks,
Steve

Roll Servo
Max Torque = 15%
Servo Gain = 0.50
Auto Trim Motor Speed = 5%
Fine Adjust Amount = 0
Fine Adjust Time = -.--

Pitch Servo
Max Torque = 30%
Servo Gain = 1.30
Auto Trim Motor Speed = 5%
Fine Adjust Amount = 1
Fine Adjust Time = 0.20

Pitch Gain
Min Airspeed Limit = 65 kt (or as preferred)
Max Airspeed Limit = 180 kt (or as preferred)
Vertical Speed Gain = 1.00
Vertical Accel Gain = 1.00
Airspeed Gain = 1.00
Airspeed Accel Gain = 1.00

Roll Trim Motor Speed = 100% (fastest, 80 kt) / 25% (slowest, 150 kt)
Pitch Trim Motor Speed = 100% (fastest, 80 kt) / 25% (slowest, 150 kt)

Walt has it here.

Yep Walt is correct. Only comment would be that most of the set-up is in the installation manual and we found that the default setting worked pretty good after getting the system up and going. We only tweaked a coup[le of the default setting and then by not much to speak of. Yours, R.E.A. III #80888
 
Firmware

Stan,
Although you are using the G3X Touch and a bit different than my situation, just make sure that you also have the latest firmware for your system. That seemed to be a pretty big deal in my case.
