dude, u need the 8psi spring.. the white spring..
-12 to -15 in/HG use 8 PSI Spring (White) <--- this
the psi for the spring is what your car pulls at vacuum. its to keep the bov closed while youre in positive pressure and to not open up while its idling.
hook up a boost gauge and select your spring on whatever in/hg youre pulling @ idle.
as for sound/performance.. it depends what you want. HKS will let everyone know youre coming.. there are inserts that you can put on that will make it less of a chirp and more of a low pitched whoosh sound.
TiAL is more of a trtrtrshhhh sound and at high boost you can barely hear it its more of a higher pitched TSHHH like you opened up a bottle of coke.
lol i feel stupid trying to describe a bov's sound. you cant go wrong with either.
