i bought the car with the hks blowoff valve already installed, so i don't have any instructions. i am experiancing a slow leak somewhere in my system. when i looked at this picture on mkiv, i may have found the problem, or part of it. if you could look at the picture and tell me where to route a vacumn line that would be great (pic even better)? right now i just capped off the flange, and i get a little more boost out of the turbos.

Is this the HKS Racing or HKS Racing II? I had a Racing I and it couldn't hold higher boost levels so I replaced it with the Racing II and everything is fine.
