I would be worried if you're running 12.5 afr under full boost. That's a little lean, you should ideally be around 11.2-11.5. Maybe clean your AFM? Then check your wastegate lines. One of my bolts holding the wastegate to my housing stripped once causing overboost. Maybe swap wastegates? I don't know man. That's a weird issue.
As far as riching out when you shift, that's normal for atmosphere vented cars.
