wrx coilpacks

So suddenly my car is no longer boosting 1.3 bar, but rather only around .7-.8. I've checked all of the lines and everything is still setup correctly. Did a sensor check and the boost solenoid is still working. AVCR is on with target boost @ 1.3bar and all of the duty cycle numbers still inputed (i.e. it wasn't turned off by accident). What should I do? Is there a good way to figure out what is wrong? Is it common for the AVCR solenoid to fall apart? Could it be my sparkplugs (BKR7e .028 1.5 years old 7k miles)? I do have a MBC and have long considered removing the AVCR in favor of it (GFB atomic)
