So when in my parking garage or even say a parking lot or just crusing with low rpms I will occasionally hear a weird sound from my Boomba BOV. It will do the typical small vta sound but then occasionally it's like a sucking sound for half a second giving the gas pedal a tiny tiny bit more pressure than say resting your foot on it. It sounds like pssssht then wisssssshup. I will quickly punch the peddle sometimes after I hear it to make sure it closes when I give it throttle and it sounds like it's snapping shut because it stops exhaling. Anybody have the same thing happening or is this abnormal?

Mine does the same thing. I think if it starts to vent and you get back on the throttle lightly it will not close completely for a few seconds. I wouldn't worry about it

This is fine. It's basically when you're on the threshold of releasing pressure (Roughly -2.0 psi or so) and just lightly on the throttle...so when you let off a hair but stay on the throttle it tries to release then kinda realizes it doesn't need to. When you're that low of pressure however it doesn't make any difference.
