I know there has been much anticipation for this TK rollout. But just remember, the TK experience you had at TrackAttach may be quite dissimilar to that which is ultimately certified and approved by CARB. It was certainly a pre-certification version loaded into the Miller cars.
Owners expecting the FR500 race car tune due to the marketing claims made 10-12 months ago could (or did) not anticipate the difficulty in getting this dual path programming logic through CARB. With the intense pressure from all the Boss owners to GIVE US OUR TK, who knows how easily Ford Racing compromised the original software to make CARB grant them certification and get the owners off FR's back.
