    Assuming you mean the breather mod. I've got a catch tank in the engine bay.

    Lol I mentioned lack of cup mod posts to a fellow member tother day. Now we got one, I deem it a good thing I think there's a top article on it, I ran it for years with no issues, but any gains... Debatable

    It says in the article on cup mod about if u use a bleed valve it can cause waste gate creep, and fuel vapour. Main reason I'm doing the mod is so I can use my crome lobster neck which don't have the right size port 4 the actuator. Was just wondering if I should do away with bleed valve for this mod. Cheers.

    IMO get rid of the bleed valve, just adjust the actuator to set the boost. I never see the point of having set up the fuelling for a certain boost level why you'd want to fiddle with it.

    Once you do the cup mod, the boost drops down a little, so you need to wind the actuator rod in anyway.
