slammed 66

Just after a little advice if you can help please. I've just been and left a deposit on a very nice '96 WRX V limited (not sti or RA) The car is great and drives spot on but it's not making much boost. Only about 4psi according to the factory boost gauge. What boost pressure should a jdm wrx be making? My gut tells me it's most likely the boost solenoid that's at fault or the wastegate. Thanks Ross

dont know if it helps atall but the chassis code starts GC8032***

Hey guys, i might be buying my next impreza tomorrow but before i run into the purchase can someone confirm if this is an STI and if so which model and standard power output. Thanks very much Ross
