Theres one on elizabeth lake rd, its a mustang shop. Not sure how they are, i stopped in the other day to talk to them about it. I think it was $125 an hour with tunning, and then $325 for a chip if they need to burn one.
You've also got Alternative Auto is in Mt. Clemens www.alternativeauto.com, Paul's in Jackson, and Livernois Motorsports is in I believe either Dearborn or Derborn Heights.
Well I called around, found that place on Elizabeth Lake rd. called Nelsons Performance. They said 65 bucks for 3 pulls for a baseline. They said they use a DynoJet, I am not an expert on dyno's so how will this dynojet compare to another dyno?
