My GTI makes a hissy noise at high RPMs. That's normal with a turbo, right?
that's the stock wastegate bleeding off excess boost so your engine doesn't explode before your warranty expires. If I recall correctly, Forge used to make an adjustable BOV with different springrates to regulate how long the system will build boost.

Bit late - I have the Forge Blow-off valve was great for about 3- 4 weeks now; i'm so pissed off with it that i'm taking it off.

Anyone want to buy it from me? are more than welcome!! ?20 and its yours call it ?5 for postage too. (its ?50 from www.awesomegti.com)

It's ok sounding i do love the TISShhh but some times i don't want the TiSHHHH - but alas i still get it.....

I'd say forget the Forge.. get the NEUspeed Induction Kit.... now that sounds better!
