So I just recently installed a Greddy FV2 BOV on my 99 GS-T because the stock BOV was shot and I figured instead of going with a 1g bov or another 2g, I'll just get an aftermarket one why not, and I'm not sure if this is an issue with the BOV, or if this is what the BOV is supposed to sound like, or if it's possibly just the turbo (stock turbo), but on lower end of the boost gauge it makes a flutter sound, and on the higher end of the gauge it sounds as if it should sound when it releases air (I don't have aftermarket gauges yet, and I know how janky the stock gauges are, they're on my list of the next things to replace)

I'm not looking to have a flutter sound, I want it to sound like it's supposed to sound, and I've adjusted the valve loose, tight, and everything in between to see if that'll eliminate that flutter, and it seems as though it hasn't made much of a difference regardless what I adjusted it to.

So I've been wondering, is that particular BOV supposed to sound like that, or is my turbo starting to go bad? (Turbo upgrade is on my list of parts to get too, looking at a 16g to replace my t25 with)
