You have a couple options. You could get a mail order tuner from Justin at VMP, or take your car to a dyno shop and let them do it. But you need to remember that a dynotune should only be done after you buy a hand-held tuner. Bottom line, it will be around $500.00 for both, or just 350+ for a SCT or Diablo tuner.
