I need a shop that will figure out the rough running problem and then once it is running decent can do a dyno tune on the fully broken in motor. Some more information;

I have a 94 LT1 383 stroker with a supercharger and I'm looking for a shop in Central or Northern California that can diagnose and tune it. I had the car tuned a few years ago on a dyno by newtech performance, the motor was not yet broken in so it was very conservative. I drove it only 3000-4000 miles over several years and it ran fine until the last few hundred miles when it started running richer and richer. The last two repair shops I took it to couldn't tell me anything about it running rough and rich other then to take it to a specialty shop. I would take it back to newtech performance but they don't do repairs. Any suggestions would be greatly appreciated.

How does your setup add the extra fuel for boost - FMU, 2-bar MAP sensor, etc.?

Do you have a way to check the fuel pressure, under light load driving, and with the engine under boost?
