The square hole at the edge of the stock BPV/BOV
Hi all,
Just noticed this morning when i first start up the car, i can feel air coming out between the BOV and where its mounted. Upon close inspection, the air's actually coming out of the tiny square hole at the edge of the BOV (That hole's there from stock)
Is this normal? I mean, do anyone know what's the purpose of the hole there? The air seems to stop when the rev get back to normal idle rev range........which means it might do exactly the same if i start revving up??? a.k.a Boost leak??
Note: I had a CPE FMIC on, so not sure if its the fmic or the bov?

When in doubt, power out....of control.
