I've heard the same rumors. Apparently, it's a variation of Ford's "MyKey" technology which will allow Boss owners to unlock additional performance from the vehicle. Likely, there is a calibration that allows the car to meet the EPA standards required for a street-legal vehicle and another "off-road only" calibration for the track. It very well could allow a higher rev limit as well as some tweaking to the traction/stability control system. We'll all just have to wait and see.
