Hey, im really not sure what to do. I just installed my hks ssqv bov and it holds boost great and everything but i can not get the correct sound? Even at 14 psi i get the studder sound. I guess the large valve is not opening and i dont understand. I had the screw in back in the middle and then all the way out practically. ( i didnt try all the way in) All i get at 14 psi is a louder studder with a littttle slight woosh.
Can anyone help me fast????!!!!???

What exactly do you mean by the "studder sound". I also have the HKS SQV and I like to compare the sound to a cracking of a whip. You definately know when the large secondary valve will open. I never had to adjust my BOV, it came perfect from the factory. Make sure that the vacuum line is correctly attached to the back of the BOV. Also, don't screw the rear bolt in all the way. That will increase the spring tension inside the BOV and will make the valve harder to "respond" try taking the screw out counter-clockwise to decrease the internal spring stiffness. Also, keep the BOV. it's bada$$ and scares people!!
