Dyno shop? Where?

Dyno tuning is great, but most things can't really be tuned. The computer will adapt to most changes you make. Base timing is probably one that you can tune on, though. The more valuable information would be what your power band is and trying to isolate what your bottlenecks are.

Here's a blurb from Ford Fuel Injection and Electronic Engine Control:

Drivers who driver their adaptive-system cars to the drag strip are often puzzled about their high elapsed times. The system adapts to street driving. When they run the strip a few times, the control module re-adapts to the strip, and their E.T.s improve.

A dyno is almost like doing runs on the strip. You may be changing things and your power is improving, but it may be nothing more than your computer adapting to all the WOT runs. The only way to really make sure that the changes you make are making a difference is to reset the computer before each run. This way you know that the computer is starting from the same base line each time.

Just in case Mach 1 reads this, the above quote clearly indicates that adaptive strategy even applies to open loop operation.

Oh, and here DynoJet Facilities in New York
