It all depends...If your turbo is too big, you wont build up enough boost when the car isnt under a load. My car doesnt blow off at a stand still and I run 17 psi. Take for example...A wrx has more displacment than your civic and a fairly small turbo. He builds more boost at a stand still and has a smaller turbo therefore blows off while standing. Does this answer your queston?

So you just want to sit still, rev up your motor just so you can hear your BOV??

a stock wrx bov is recirc so you cannot hear it, you can hear an after market bov on a wrx because f like they said more displacement and a smaller turbo
