So you're really just trolling to get a flame storm started? Because from your post count you've been here long enough to know the usual reaction to the first 4 words in your title...I'm not playing along.
Basically the track key advances the shit out of your timing and adds 5lbs of boost from the hidden small electric supercharger under the intake. It also activates The Noooosssss and your car automatically sprays a 100 shot if the other car gets in front of you. The track key has built in gps which links to a satellite which tracks your car and knows if it is losing a race.
I gave him the right answer lol ... It is just basically making the car act more like a race car with revised engine braking and other various crap that no one really knows about as well as a built in 2 step and a lopey idle. It doesn't add any power
