HKS SSQV non adjustable?

[dizbjello]

i bought a hks bov from a friend and i noticed that it doesnt have the adjustable screw on the back. did hks ever made one like this?

Maybe you have an older one or something, but my hks ssqv has a screw on the back for adjusting. Is there a hole for a screw or is it just flat?

I also have a new one that's not adjustable, works well either way on 15psi t28, no compressor surge
