My BOV gives off 4-5 blasts instead of just one big blast. Why?

Re:My BOV gives off 4-5 blasts instead of just one big blast. Why?
Do all BOV give out one blast or are there some that give out 3-4 blast? My BOV has a flat top with a barb for the hose that can be tightened or loosened. Inside it has a piston that moves up toward the cap with the hose on it, and it has 6 holes on the bottom for the exits. It has a spring inside pushing the piston down. I cut out a wind on the spring and have the BOV set as loose as possible without leaking pressure. Are all BOVs supposed to just give one blast or is mine a real shitty BOV. 
thanks in advance.

Mine lets out a loud "running over a bird" screech, then a light flutter. It's an HKS SSQV though, and that's how it's designed to work. I would try finding someone else with the same BOV as you and ask them?

i have that cheap ebay bov and i cut 2 coils out of the spring and it sounds really nice, doesnt flutter at all. im running 10-12 psi and even at 1 or 2 psi it is loud and sounds really clean
