I just bought a 02 wrx with 40k on it. The only mods I have are an intake, turbo back exhaust, and apexi boost controller and turbo timer. When my apexi boost controller is set to off, my max stock boost only reaches about .05mpa. When i turn my boost controller on and set a boost level then my car reaches the boost amount I set it at. I thought stock a wrx would run about 13psi or just short of .10mpa. The car did this before and after my intake and exhaust mods. I have looked for leaks but because it reaches boost when the controller is on I dont think its a leak. Any ideas on what could be wrong or am I just misinformed about the stock boost of the wrx? The original owner installed the boost controller, and I dont know much about how it really works.
