Hi all just need some help with my Hks SSqv, theres a bolt at the bottom of the dump valve, what is this for? does it adjust the amounth of boost it opens on etc ? just ive adjusted it to see what it was for and now my DV doesnt work and just gettin a rush noise through air filter followed by slight chatter. actually does sound good and car seems to go quicker on gear change and even a little bang as i change gear ( through the exhaust ) like anti lag lol. so my question is does this bolt adjust anything and if so what do you do and what will it do to it so to spk lol.

 

adjust it back to how it was.

 

i tried that, couldnt remember exactly wat it was set to any one know how the bolt works if it actually does nething or if its just by luck they both happened at same time.
