Is this on a sailboat or a powerboat? On my autohelm (pre-raytheon) I can tweak how the autopilot responds to changes so that it doesn't overshoot when turning, or at least it doesn't overshoot as much as it used to before coming back on course. I'll have to look at the manual to see what they call the setting, but the diagram that I do recall demonstrates your issue.
