My brother's shop isnt a dyno yet, i think those are the old dyno's. Their new dyno is a smog/performance in ground dyno. Whats cool about it is you can do so much stuff with it, even simulate your 1/4 mile run. you put in the weight of the car, air tempetures and a few other information about the car and stuff and it will simulate your ET's. So get ready guys, who all would be interested in this? location is Albany CA, next to Berkeley.
