there is no learned on the boost map to my knowledge. It will only correct through the turbo dynamics table which mean that as you are low on boost it gives you more wastegate % and if you are too high it will run the wastegate % Lower. but there is no learning on the ram that will change the wastegate % values.
since you adjusted the wastegate arm that is probably part of the reason it is over boosting. previously when you said it was surging it may have been trying to reach boost targets and causing it to fluctuate.
if you are over shooting lower the wastegate values on the map by say about 5 at the area its over shooting.
im not sure what boost cut is on that map, but im guessing its close to 20psi if its not considered a race map. you can just look it up on the map.
