my blow-off valve doesn't seem to make a sound anymore, it used to when i floored it a little, but now it's not even coming no more. i can only hear it when i rev it all up, but it's unusual to not get it when just reving it up a little. why is this? could it be because i dont have a gasket between the wg and the exhuast manifold? oh and another question is how do you adjust the hks super sequential blow off valve? is there a way to make it louder?
