Ok this may sound stupid but i just purchased an hks ssqv and im not sure on how to adjust it. From what i have read from searching there is a adjusting screw on the back of the bov well on mine there isnt. Maybe there is a different way of doing it and i just dont know cause the instructions that came with it are in japanese and of course i cant read it. My buddy said that he has seen hundreds of these bov and ever one of them had an adjusting screw on the back. So is there something im missing here? Is there another way of adjusting this? Thanks in advance.
