there's a mustang dyno at SpeedNation in McDonald. it's about 45 mins. south of pittsburgh.
that's the only one i've been to. it's 70 or 75 dollars for 3 runs i believe. if you can get a group together, it's 60 bucks for 3 runs. and every time you go back it's 5 bucks cheaper but you top out 40.
might want to check it out. i'll see if i can get you the number.
