I haven't had them work on my car but Maverick Motorsports in Fullerton has an AWD dyno and one of the guys there owns a 1G and a 2G with DSMlink. They are located at...
3811 Artesia Avenue
Fullerton, CA 92833
(714) 523-1896
You can also get ahold of Scot Gray
sgray@nettweak.com. I believe his going rate to street tune DSMlink is $300. It won't be on a dyno but it will be tuned good.
