well a BOV will not net you any HP gain's and their just a pain in the ass with this car they will give you alot of stalling problem's .it will just give you that whistle(sp)sound but, the first mods that i think you should spend money on should be the,Injen intake that will make your stock BPV much louder and, give you some HP gains.and a FULL turbo back exhaust but they cost alot of $$.you can get alot of diffrent thing that will actually give you some more power. i.e-down pipe/hard pipe kit/FMIC/boost controller.just don't go turning up the boost with out the proper breathing modification first.but a turbo timer is a very good choice.
you should read up alot more on these car's before you just go throwing mod's at it.
about the meet's go here
