If you watch Leno talking about the car around the 4:40 mark Jay makes a comment about a special key for the laguna seca version. At that point the representative shuts him off and tells him that is for another time. It definitely sounds like Leno was let in on the secret.
This is what I was talking about the rumor with the boss and the "red" key allowing the car to rev to ~8200rpm.
