Re: (jessec817)
It's just enough pressure in the charge pipes to leak/squeak/whistle the BOV, it's normal. If you tighten the spring up to a stiffer setting, you may get compressor surge.
Try adjusting the setting and see what works best for you. The stiffer the setting, the more pressure it will take to blow off. Mine blows off at >2psi, but it does whistle. I don't even notice anymore.
