I underestimated how long my visit at DB would be, but I think the results speak for themselves.
I arrived at 10a and Shane and Brian went to work installing the AMS fuel rail, Perrin 3-port, and DW800 injectors. That took until about 11:40. Strapping the car onto the Dyno required pulling part of the undertray so it was a little more time consuming than the routine at MAP.
Shane had finished dialing the fuel in and suddenly the AFRs went to 16. Shane and Brian spent the better part of 45 mins experimenting with the tailpipe o2 sensor and finally Shane threw in the towel and suggested plugging it into the rear o2 bung. When he looked under the car he discovered that the midpipe had disconnected behind the cat! In retrospect I should have known something was wrong because the car was sounding mean, I saw smoke in the wheel well, and my eyes were stinging from the exhaust. Silly me...the Specialty-X exhaust didn't come with lock washers so I didn't install any. One of the guys (John?) installed a new gasket and bolts for me (after backing the car down the dyno ramps a bit for access).
It's still a little early but my immediate impressions are that the car makes a MUCH smoother transition from no boost to boost. The Perrin 3-port is also crazy-loud. You never hear the stock boost-control solenoid but this one makes a constant clicking sound...was a bit alarming until I found the source of the sound.
