Doubtful that anything was damaged, but it depends what the boost limit was set to. With an OTS stage2 map I'd imagine it would be pretty low (maybe 20 or 21psi, but you can look at the map notes and I bet it would be in there [i run OS so I don't have much experience with the AP). What happened was a fail safe the ecu has set in place in order to prevent damage from massive over boosting.
As long as no hoses popped off or anything like that I bet you didn't do any damage to the car.
