I responded back there - I didn't see this posting. Time for new glasses again. :-)
But here's what I wrote back there, with a few ammendments:
You got me baffled. It does just what it's supposed to do and then some.
I wonder if there's an alternate vacuum hose routing. Have you looked under there and found that the pressure transducer is disconnected from the vacuum line?
Or if, as one of my EE buddies called it in class, the "psychic force" tells the APC what's going on with the manifold pressure :-) (BTW, he didn't go on to become an electrical engineer - he's in sales. heh heh heh)
Just brainstorming here - I wonder if there's a resistor in the line in place of the pressure transducer, always indicating a low manifold pressure to the APC. Come to think of it, that's exactly what having the transducer unhooked from the vacuum line would do - give a constant resistance, fooling the APC into "thinking" that the manifold is always at atmospheric pressure. It closes the wastegate further than it would if it read the actual pressure.
I'll have to try that - remembering to cap the vacuum nipple on the intake manifold, of course.
