Accessport also offers a PDK transmission tune to optimize the performance. I don't have any experience with it. However, I do have the Cobb Accessport tune on my 14' Cayman S. Out of the box, the stage 1 tune is pretty noticeable and keeps things relatively safe. If you go the Cobb route, you can also have a custom tune done specifically for your car. This can be accomplished either by bringing it to a tuner familiar with the Cobb AP product or by grabbing some data logs and emailing them to a pro tuner. They'll be able to create an "e tune" file for your AP unit and allow you to load it yourself.

I think all of the other important points have been covered.
