Got on a dyno last weekend. This is the first time the car has been on a dyno so unfortunately I don't have other numbers to compare against.
AFR's were about 10.0-11.0 according to the AEM wideband in the downpipe, and about 10.5-11.5 according to the dyno's Motec wideband mounted in a pipe and stuck in the end of the muffler (after the stock cat, stock muffler).
Ignition timing was about 3-11 degrees leading advance depending on RPM, with 15 degrees trailing split. Boost was about 10psi (165-173kPa), dropping to 7psi at the transition.
Didn't spend too much time making adjustments... it was late at night and the dyno owner was doing me a favor letting me use the machine. Boost wasn't as smooth as I'd like it to be (especially on the blue squiggly run), and I suspect there may be more power at different AFRs or ignition timing.
