If you are near Tempe, the absolute BEST place in town is SalemBoys! They have a DynoTune machine, and one of the Mechanics owns a TurboCoupe. I had my '88 at 3 other places with a problem that could not be pinpointed. One of the shops wanted to sell me a NOS system, because that is their specialty. I had it at SalemBoys for 20 minutes, and they found a loose bolt holding the Turbo in that cause a leak under boost.
