i have an 02 wrx wagon, a while ago, i got a turbo xs dual stage boost controller, i put it it, pumped up the psi to about 15 psi, then killed a clutch. got new clutch, took out boost controller, and VDO boost gauge showed i was running around 5.5 psi, tried that for a while, but got pissed, so i put boost controller back on, and tuned first stage to 12 psi, and 2nd stage to 16 psi . posted about some bogging issues in dual stage, and cel light comming on, so i took out boost controller again to take it in to shop, but never took it in, so i put it back on just like i had it before, only this time i was pushing 20 psi I promptly got off freeway and put stock hoses back on, which i have on now, but im still only running 5.5 psi, anybody have any ideas whats wrong? i have an injen intake, apexi safc, blits nur-spec cat back exhaust, and hks ssqv bov, also a grounding kit, but i dont know if that would affect boost levels that much.

 

5.5psi.. that is below wastegate pressure... you may have a problem w/ the wastegate actuator or BCS or a restrictor issue or a combination of these... where are you measring the 5.5? The stock wastegate spring is about 7 so even w/ no boost control you should be able to hit that.
