DarkWolf said:I just did the mod and blocked off the reference port and didn't bother to drill a new reference port since I know I am to lazy to use it. Do you need that for some reason? It doesn't seem like doing it my way really did a whole lot. It still acts exactly the same at low boost and I think it is still leaking at 18ish psi just not as much. I am using a cutout raiser and before the mod I couldn't hit my raised cutout and now I can but it does so slowly. Just need to know so I know where to look intercooler hose leak or bov leak. Pretty sure I hear something leaking.
That other reference port is to make the BOV act fast, IE it reacts quicker. The way you have it now, it will hold alot of boost, mine held to 29 psi but it reacts slower so in some cases, IE lower boost, it will cause the turbo to chatter/stutter. If yours doesn't, its fine.
