when i first put on my hks ssqv, it sounded like it should. fast foward a few months and it kinda sounds like its surging. so i swapped in another ssqv to see how it would sound, same thing, if not worse. i've tried adjusting the screw on top, which doesnt seem to do anything. im using vacuum from the vacuum block, so i tried using the vac from the tb and even that made it sound like its wasnt even working at all. i pulled apart the bov to see if maybe something was wrong internally, but it seemed to be in working order. im not sure what to try next. any ideas?
