I got mine done last Friday. It gave me an extra 25 horses with the tune. I would definitely recommend it. I got the dyno tune and it took them 7 hours to finally get it done. Orininally, they told me that it was a 2 hour job, but it turned into a 7 hour job. Just keep in mind that this is not a quick job and I wouldn't recommend waiting around the shop like I did. I replaced my headers, exhaust, and CAI so my check engine light came on, but with the tune, they where able to remove the check engine light so I don't have to stare at it everyday now. I do have to hit the ESP button everytime I get into the car which is annoying, but I can live with it. You definitely notice a difference sitting behind the wheel. I would recommend it.
