I use the turbosmart valve that came with the kit ... and tighten just a turn past the rubber o-ring ...very little if any flutter and then it's at a very low rpm if it does. I did have issues with it sticking for the first 10k miles but each time it did I took it apart for cleaning and re polished the brass piston now it seems to never stick anymore .... knock on wood ..as far as loudness ..... it is very loud and very noticeable .... if got want to make it quieter you could attach a hose from the bpvand route it further down the car ... but for me I love the sounds and loudness of it ...can't really hide the whine of the supercharge so with out the bpv sound it would just sound weird to me
