I think that they have that on K&N's website. I use Airaid and the most noticeable improvement was in throttle responce.

You get maybe 6 or so HP without custom tunes. With custom tunes, maybe 12 or 13. You can not go by what is on their website. The guys doing tuning have dynoed and that is what they reported.
