that is a good question actually however that i am not sure i just know the the normal dlc one pays for is yours from the moment you get it and can be removed and reinstalled at anytime. the cards dlc however i would imagine is same basic concept just not sure how to find it. however maybe since the code is now linked to your GT maybe type it in again while it wont work for anyone elses GT it may work for yours im not sure...good question ill ask around and let ya know if i find out anything. never thought of it tbh.
