I have not really had any issues from reman ecm's purchased from a dealers#it, but have heard of it happening on the odd occasion. - Just make sure they pre-flash it with your trucks software and settings before leaving there with it. This ensures the ecm is at least working and is cheap insurance against them accusing you of doing something to it / denying a warranty claim if it is a dead stick on arrival. Bang the top of it to test it when u install it to ensure its a good one.
