It sounds like you're stuck at base boost, which means that the APC box is essentially sitting there passively.
The things that cause base boost range from unplugged APC box (seriously, the connector sometimes falls off if it's not firmly latched), stuck brakelight switch (btdt), through bad knock sensor cable or knock sensor, to a bad or sticky APC solenoid. (The brake light switch would be kinda obvious.)
Before you do *anything* with the wastegate, make sure that you have a full and proper tuneup and check everything in the basic boost FAQ. Follow the link below.
