I know Unitronic and Integrated Engineering offer at-home "Dongles" that they ship to you, and they provide full, easy-to-follow instructions. Basically, here's how it works: plug the dongle into your OBD-II port under your steering column, plug the dongle USB cable into your PC, install and run the Tune Software program they email you, and then follow the instructions on the program.

The only thing you will need while you "flash" is a car battery charger that you can hook up to your TTS' battery and plug into an outlet (I bought mine at Kmart for $24, and you can use it in the future for charging your car's battery when it gets too low). The battery charger will ensure your battery stays fully charged WHILE you're flashing (like I mentioned, flashing can take up to 30 minutes), so that the battery does not die, which will be problematic for your ECU. I have never had any issues, and as long as you hook up your charger to your battery, you'll be fine.

NOTE: If you purchased your TTS with an Audi Warranty or Extended Warranty something, and you later bring your TTS into an Audi Service Center for any maintenance that involves them checking the car's computer (ECU), Audi will notice that the car has been tuned, and they will void your warranty. However, thankfully, my tuner (Integrated Engineering) allows me to "flash" my car back to the Stock Settings, so I never run into this issue.
