BOV Sound

Could someone tell me if its normal to have no BOV sounds with car at park while reving after FBO install?

all stock with BOV i used to hear the whoosh just revving, now with DPs, FMIC, DCI...no sound, only during driving? when i run hard i can see the boost gauge holding boost? is this normal, do i have a leak somewhere?

Try revving the engine and let off, then quickly give it a "stab"(before the revs drop) and release the throttle again. It should blow off.

our cars build a very small amount of boost without load. You gotta rev it up pretty good to hear anything though.

You need load to build boost. It's probably harder to hear the small amount of pressure generated now while in park revving.

If you start at idle and go WOT quickly till about 4-5000RPM and then let off quickly you should get about 2-4psi.
