Its a much more capable-then-your-average OBDII reader. If you rely on someone else to read your error codes at a cost, you should sell your call now. My audi dealer is 173/hr and they dont read codes for free. There great cars but finicky for sure.

Its not a cable to flash tunes.
Cool, thanks for the info. So basically the most advanced diagnostic tool you can get, plus the ability to change some things, just not do tunes. Guess I'll be ordering one today.
