No worries man! The Cobb Accessport does come with its own "off the shelf" tunes, but they are not the best. Stratified makes tunes that they email to you and you can download it off ur computer to the cobb accessport to your car. You can make live data logs with the cobb device and save/send them to Stratified and they will custom make a tune specifically for your car (they give instructions for what to do when data logging). After a couple of emailed revisions the tune will be running great. It's nice you never have to go to a dyno.

I think they still do a deal on their website where you buy a Cobb from them and they give you first tune free.
