According to my pfc im only gettin 7.3 psi (0.52kg/cm2), i should be getting 10psi right? Could there be something wrong with the pfc?

 

There could be something wrong with the PFC; however unlikely. Get a boost gauge and you'll know for sure if you have a boost leak. These cars are prone to boost leaks, therefore if you have one, you wouldn't be the first one.

Are you bone stock. If so, look into getting a hose job to replace all of the rubber vacuum lines. If not, then get a flashlight out and start looking because there's not that many places to look

99% chance you have a boost / vacuum leak.
1% chance PFC is bad.
