Just installed my Mishimoto Cold Air Intake, it sounds great but I know I won't really see any gains until I eventually get her tuned. I'm not quite ready to void the warranty with a custom dyno tune so my next step will be to install the Vitesse Throttle Controller to see how that improves on performance. I've hear do some people seeing some gains on their quarter mile times and even 0-60 times using that so I'm going to give that a try.
