of course the more mods with pulleys headers software downloads and such will gain hp that is what they are designed to do especially when u get them all working together and tuned with each other and software changes. all i was saying is i find it hard to believe that just a CAI was gonna gain 13-17hp in these cars but if it does then great!!!!!!! remember i own one and i love hp so if it gains hp or heck even if it was to gain MPG then i say HOOOOOOOORAY.
i have a bmw and it has many many many mods so i am fully aware of what mods can do for a cars performance.
congrats to all who have one and get whatever gains come from this kit.
