You know my friend, the Code 3 gives you a little more power, and I mean a little. I like it because it looks stock and I don't have to pull it off if I go to the dealer, being in warranty and all. If you really want to feel a difference go with a crank pulley. There are numerous posts that discuss this option and the pitfalls involved. The benefits are obvious, a lot more power. Remember, read all the posts so you don't mangle your engine or engine bay.
