I just installed my 65mm TB. What a pain in the ars that was. Direct bolt?...yea sure. but anyways i got it on and everything is very secure and snug. When I start the car on a cold start the rpm's drop to around 300. Once it sits i give it a quick rev and it ll idle fine. Then once its idling fine I can hearlike this air leak. I guess its coming from the IAC(piece right behind my intake manifold). It just leaks a little bit of air. Do I have to adjust anything after the TB was installed.

BTW...car is a `99 Cobra.
