I do not have a 91 9000 but something is way off. If you are hitting 22psi and it is then going down to 12 then your apc is dectecting detonation. Adjust your baseboost down some so it is around 8 psi and see what that does. Sounds like you have way to much overshoot. Can you adjust the pots in the apc like the old 900's?
Can the ignition be retarded manually on your car?
I had the stock turbo (not sure if it is better or worse then a 91) on my 88 spg for 220,000 miles and with my setup on 91 octane gas I could hold around 18psi with hardly any overshoot.
