Mine has an adjustment bolt on the backside. /ubbthreads/images/graemlins/dunno.gif
So did mine and I bought one right when they came out. Mine also never said HKS (sticker) on it IIRC.
The OLD HKS ones did. With the last batch of the SSQBOV v2 and new v3 like the one on mine, they have eliminated this adjustment as it proves to be more of a nuisance and people destroyed the BOV, I guess...I called and talked to HKS tech about this and thats what I was told...
