Im really confused as to why my hks dump valve dont seem to dump very loud. You can just about hear it after full boost but you still get the turbo chatter as if its not realeasing enough pressure. Ive added a picture to show my layoutimage.jpg

I was given it and they said it was genuine mate. Any way i can tell? It use to be louder on the tt setup if that helps? The vacuum travels all the way to the back of the inlet. Does this matter?

my HKS valve the same as yours doesn't seem that loud either I just thought the race valve wasn't at all that loud

Is yours genuine? Its not because its quiet. I just dont think its doing its job
