fluttering sound from BOV? (was: Noise!)

At low RPMs, as I let my foot of the gas I get this fluttering sound. Not quite the BoV sound. I'm worried it might be back pressure. the sping tention is at max loose on the BoV. could it be a vacume leake? could it be an intake problem? I've confirmed no exaust leaks.

it shouldnt be a big problem my car does that i think all it means is that theres not enough pressure to open the valve, but my spring on my blitz BOV isnt at the max loose its in the "medium loose"
