"I have always run a one-way valve in the vacuum line from the throttle housing to the turbo distributor to eliminate vacuum advance (but allow boost retard). Have you tried this?"
I tried defeating the advance with a valve, but when it closed, it held steady whatever timing setting it was at. Instead, I ground down a washer, cut it a bit, and press-fit it beneath the notch in the arm; this mechanically defeats the advance instead.
I easily passed WA emissions with 23#/hr with the Saab NA ECU; because the Volvo easily maintains closed loop at idle/low revs, presumably I'd pass with it, too...
