That noise is coming from the sorry Bosch BPV TRD put with the kit. Buy this one and install it and you won't hear it any more plus you will regain some of your power lose! http://www.hoppenmotorsport.com/bypass.htm --- Get the Bosch 110 Sport .

BPV = By Pass Valve - It recirculates unused compressed air. Normally used on Superchargers but can also be used for Turbo applications.
BOV = Vents unused air out - Mostly used on Turbos however a few Supercharger have been design to use BOV like the company Vortec

I'd go with the Forge 007 "bunnyfart." The Bosch 110 Sport is good but it wont last too long, especially if your running the 9psi pulley. I tore the diapragm inside the Bosch 110 I had on. Its plastic and it will eventually go. The Forge 007 has a real piston inside of it and the entire BPV is made of Aluminum instead of plastic. The Bosch 110 will cost you around $55, and the Forge 007 will cost you around $115. Just my 2 cents.

Yes, check you local Performance shops for the Forge, Bosch and other compatible BPV's. Note too that the BPV is also known as a Recirculating Valve. It can also be bought at any Nopi performance retailer near you, or get it off eBay like I did!
