Type-S Question

[TsiEagleTalon92]

Does anyone with a Greddy Type-S BOV have a odd sounding noise after doing some moderate to hard boosting then to a coast? It seems to me that after I do so, I get this weird sound. It is kind of like a constant whistle that can last up to 7-8 seconds or until you even tap the gas then it is gone. I am pretty sure it is nothing serious, But I am trying to understand my car more.

How is the vacuum line ran? If possible give it its own vacuum source from the manifold with no "T"s.

The vacuum line "T's" with the hose going to the manifold on the left and the boost controller on the right. So this would mean I have to drill and tap another hole into the manifold?

Maybe it's set too soft. My friend's generic Greddy type s makes a long, whistle noise when it shouldnt be making any noise at all. I think in that case its due because its just a piece of shit knock off.

Im assuming this is for a 1G(judging by your SN) cant you put the boost controller inbetween the Jpipe and the WG? and run the BOV straight to the mani? I dont know your set up so Thats the best I can come up with.
