Hi all, I’ve got a 32 gtr it’s has pod filters, turbo back exhaust, rebuilt turbo’s and niztuned ecu. It’s has an Apexi avcr boost controller and is set to 1.25 or 18 psi was running fine for about a year or more but has slowly started to creep up was going to 1.35 but now going to 1.50. Just wondering if this could be caused by leaking vac hose or a sticky solenoid. Any help would be much appreciated.
