what kind of power increase do you get from it on a stock 400
does it rev quicker or does it give it more horsepower.

On an otherwise stock motor it will rev up a little quicker bottom through top. Must add a little more power, since it revs up quicker. Not a big improvement - just noticeable.

I got an Ignition Advance Key and I couldn't really notice much of a difference. It was kinda a pain to install because we had to use a torque wrench. If you don't know much about engines, get someone to help you who does. If you don't know anyone who knows about engines, I wouldn't recommend getting it.
