You need to go to the homepages of the tune you choose and see where is thier closest distributer. If you plan on going GIAC, you should also check the classified section in various places that has previous owners selling thier ECU with the flash/chip. Ebay has them all the time. You could also check the AZ classified and Fourtitude.
Example
Example 2(I noticed that it brings you to the search page. type in "GIAC" in the search and scroll down to a4,s4,rs4 B5 classified subforum. edit:upon closer observation, I see you already did)
And if you don't want to go that route, check
this map for closest dealer. AWE is just one distributer out of many.
Edit: Ok, I got bored and felt like searching for the closest GIAC distribiuter for you. It is not that far from you in Cheektowaga, NY.
Here's a link to thier website.
