I just bought a 2008 wrx hatch. the only mod is a cat back. its only hitting 9psi boost. i have a gauge pluged in to the obd2 and it says the car is only requesting for 9 psi when i know it should be asking for 11.41. ive looked for boost leaks cant find any i have replaced vacccum line even bought the new t fitting with the boost pill and ive reset the ecu i cant get it to ask for what its supposed to. Im thinking its in like a low power mode?
