Two things you should do after installing a Cobb AP:
1. save the stock ROM dump to your PC or dropbox or some place safe.
2. write down the serial number.
This way, if the AP gets stolen, you can still flash back YOUR CAR'S factory info instead of having to write a generic flash, and Cobb may be able to help you with a replacement unit instead of buying a whole new unit at new cost. I'm sure stolen AP's have happened before. Best of luck to you OP.
