I had a similar problem. I purchased a chip that I thought was for my ECU, later to find a small faded sticker on my front crossmember stating a re-flash. It back-fired so bad trying to start, my starter housing cracked dropping fragments into the flywheel locking up the engine. I even tried to push start it. That was a lot of fun locking up the fronts with a buddy helping me push it in the middle of the night.

Anyway, I contacted Superchips directly and they were a big help. They reflashed it for no additional cost other then shipping.

I recommend looking around your engine compartment and if all else fails, you could take it to Ford to reflash to a know code and have your superchip reflashed accordingly.
