This Red Key Turns Your Boss Mustang Into A Race Car

This Red Key Turns Your Boss Mustang Into A Race Car: "Each 2012 Mustang Boss 302 will come with an all-black key that'll work just fine to turn on your car, giving you access to 444 HP of streetable power. But, thanks to a joint project between Mustang engineers and the Ford Racing dealer network, you'll be able to buy the TracKey that'll give you a second set of PCM software instructions. This TracMode software alters more than 200 engine management parameters, increasing low-end torque and turning the Boss into a competition-ready track car — complete with a two-stage launch control feature similar to that used on the Mustang Cobra Jet."
