I have no personal experience with them but coincidentally just yesterday I was talking with a Buddy of mine who runs a local (not to be named) hot rod shop and he said that they ripped him off on dyno time, they "tuned" his car but wouldnt tell him what they did, they didnt explain the dyno sheets and the entire process was only like 25 mins long and they charged him like $170 for the dyno and $70 for the tuning.

They wont ever see me walk through the front door.
