    But you won't mistake the waste-gate noise for another one.

    Mod's, can we sticky this one? It's a good conversation about BOV's, especially the FORGE type, that peeps can go to instead of asking with colour spring to use...!!

    I run a forge v2 with blue spring 2 shims.. I played around a lot with this and ran logs to see if I could tell the difference. Can't really tell a difference between the forge and the stocker, the forge MIGHT have held boost better but it's too hard to tell and it really depends when you hit your boost targets, noise is definitely louder though. Changing springs/shims I felt no difference from blue no shims to blue 2 shims. I'm not tuned yet but I would imagine running higher boost an aftermarket bov/bpv would be more desirable.

    Got the Forge BOV in now. It's V1 I think, Doug's old one. Blue spring in. Only noisy on med to high boost, around town, in traffic, it's quiet. Perfect.
