chip?

[embler]

I was looking through a mustang trader recently and saw an ssp in there. it listed what had been done and it included "police interceptor chip". what I've always heard is that the ecu and drivetrains were stock mustang fare, except for the optional 3.08s in the rear which was something ford did anyway. I always tell people this but few believe me. did any come with a "chip" at all? please enlighten me on this.
