Aero boost problem fixed-finally!

Some people may (or may not) remember my dad & I posting a series about low boost in a '95 Aero. We pretty much swapped every removable piece of engine management hardware with my mom's '94, and had settled on the ECU as the probable cause. I remember seeing another old post about something that controls the BPC solenoid to dial the boost up or down, and we theorized that my car was dialing boost down, but not back up. We could kind of see that this was happening by tapping into the wiring to the BPC valve, and could see that only one circuit was being energized.
Well, I bought another ECU about a month ago, and finally it was warm and ice-free enough to try it today (did get momentarily stuck in the driveway on the way home, though)
Bottom line- more boost is better!!!!!!!
Now I need to get real tires-full torque kind of overwhelms the crappy old all season tires that came on the car. On the plus side, it's kind of cool to be able to get wheelspin in 2nd and 3rd after driving a 9000s for the last 3 months.
