one thing to note, i have been too three dyno days at psr and i can tell you that they move through all the cars very well, the whole process of hooking up, dynoin' and un hookin is like a very well oiled machine. they have this down pat. no one will be disappointed. we had 20+ cars from my mazda club down there in march, and no one left un happy. infact the gang has been on me for setting up another dyno day in the fall.
