So just to be clear the drive sync uses the digital senders off the drives for trim position reference correct? My only concern is my senders don’t seem to be perfectly accurate. I can adjust them so they’re outputting the exact same voltage through my scan tool then I trim the drives up and down once or twice and they’re a little bit off. So if the drive sync is using that signal the drives still may not be trimmed perfectly even?

The inconsistency is likely variation in the trim pump motor.
Yes, the drive sync uses trim sensors to adjust (almost exactly). It commands the pump to operate until trim sensor readings are same. It flat out works.
I had trouble getting my drive sync to work properly. Mike went to my boat to confirm for himself, and discovered I had a bad trim sensor. Once that was replaced, everything works great.
