An accessport is a small device that connects to the stock ECU and uploads a custom engine map to it. You can load the stock map back on at any time.
Cobb provides "off the shelf" maps, which will improve performance if you follow the very specific modifications they specify in their map notes. A better option is to have a professional tuner create a custom map for your specific car, which can be saved on the AP and uploaded to the ECU.
If you have a completely stock car, you can use Cobb's Stage 1 map, which smooths out the powerband and adds some more power and torque. This is what I have on my 2003, and while it won't suddenly give your car superpowers, it does give a noticeable power boost, and like I said, smooths out the power band quite a bit. Lots of people say Stage 1 is "how the car should have come from Subaru".
The AP also has data logging functionality (helpful when troubleshooting and tuning), and can readback some engine data like boost, etc.
So yes, it does significantly improve performance, but think of it more as the container for the real star of the show, the tuning maps, which is really what you're paying for when you buy a Cobb Accessport.
Cobb is like the "Apple" of the tuning world. The Accessport is dead simple for anyone to use and works great, but the simplicity comes at a price. Open source tuning is much cheaper (<$200), but "there be dragons ahead..."

Let's play nice...
Missed this thread earlier. Welcome to the site!Originally Posted by bradboyd80
You're pretty spot on for a "newb"
The AP should come pre-loaded with a few maps (likely StageI and StageII). Other maps are available for download off their site, and some vendors sell third-party maps (e.g., Torqued Performance) you can load as well.
