This is expected behavior. When you alter speed or drive trim (especially both), the trim tabs will need to be re-tuned. changes in tide, current, wind and wave angle will also require re-tuning the tab's attitude. It is what it is. Get used to working trim tab, drive trim, wheel and throttle as part of overall and regular boat handling.
