Well it's just like the intake + tune from FRPP you can get from the dealer. the only difference is the key changes the tune instead of having a hand-held tuner.
You can get any of these, non-warranty voiding, installed by dealer, as a "dealer option"
you can order the track key here:
I wouldn't consider it (track key) stock for the purposes of "factory stock" 1/4 mile times. The track key is not a factory option.
The reason it's not Factory stock is because it doesn't come from the factory like that. You have to order it separately, and you can order any of those through the dealership and have them install it, but it's dealership installed, not factory installed. It's no different than asking my dealership to install the frpp supercharger on mine, paying the insane price, and claiming "factory stock".
