When you take it apart, use your torque wrench in reverse to find out where it is currently torqued to. Start at 30 ( which is the lowest setting on mine but yours may have a lower start point) and then increase bit by bit until it comes free. Alternate back and forth as when one come free, it may put additional torque on the other or return the one to break first back to that setting and proceed to find the break point of the higher torqued screw. I don't know if your synthetic is pillar bedded but this is what I did. If your synthetic is pillar bedded then just take it apart but I would not re-torque above 55.
