Hi everybody. I need help. I have an s14 sr20det with Greddy RS blow off valve and Apexi AVCR boost controller. The boost controller was set to 1bar with solenoid duty cycle of 62%. I was always getting 1bar of boost reading on the boost controller screen. My Greddy blowoff valve is recirculated because it was leaking, anway regardless I was getting 1bar on the boost controller and then suddenly today not getting more than 0.78bar, no settings were changed. I checked all the vacuum lines and there are no holes or leaks.

Any suggestions for a quick fix or something I am missing? Thanks guys

BTW I don't have a separate boost gauge, I use the reading on the AVCR boost controller.
