S14 sr20det high rpm breaking up andvtec
So I know the vtec in the title will catch some eyes but that's exactly what it feels like. At 4k rpm my boost goes from 4psi to 7 idk why my boost is constricted until exactly 4k then itfee ls like a vtec pop. I know I have a leaking bov that needs replacing it causes a rough idle I'm assuming from lost metered air. 135 psi compression across the boar. Recently in the high rpms my car will break up all plugs areclean and good. Cleaned iacv, mafs, and Tps withprop er cleaning agent. Any ideas? Ty
