You may already be aware of this, but in case you're not:
- your car is new enough that you'll also need the OBD bypass link
- your ECM is locked from the factory; will need to send it someplace that can unlock it for you, or purchase a "blank" replacement outright

I've looked into "a tune" for my 1320, but haven't taken any steps in that direction since it's still under warranty thru EOY. Seems like there's a mix of people using the HP Tuners and DiabloSport hand-held tuners, plus something of an aftermarket for people who do custom "by mail" tunes.
