Rotax 582

Having issues with my Rotax 582. Up until four weeks ago everything was running fine, my EGTs and CHTs Temps were within specs and even across both cylinders at cruise.  Then I started having issues with my probes. The issues with the probes turned out to be broken wires near the probes. I replaced all the probes, changed out the spark plugs and rebuilt the Carbs, since then my Mag cylinder has been running about 30 to 50 degrees Fahrenheit hotter on the EGTs then the Prop cylinder, the CHTs are still pretty close to each other.  I’ve done the following to try and diagnose/fix the issue: Checked the EGT probes against one heat source, swapped probes at both the Muffler and the wires leading up to the MGL Gauge, swapped carbs, swapped spark plugs, changed out the spark plug wires, ran the engine briefly on one Mag to see if the temps would change, did a compression test, did a vacuum test on the case, weighed the floats, checked the height of the petrol in the bowls, did a pneumatic sync of both carbs and changed out the main jets.  So far nothing has made any difference. Anyone have any ideas?
