Default please help guys

alright i installed my upper and lower typhoon intake....when i fire up the car there is an extremely loud whistling noise that is constant.....it sounds like its coming from behind the manifold....ive checked the pvc lines and vaccum lines coming out of the upper manifold....the sound is very annoying and it gets higher pitched as you rev the engine....what could this be??

how about you ask less questions, and just do what I told you to.

Im not some scientist that understand the exact airflow into the intake of your engine... all I know is... you get a whistle in your intake... you drill a 1/8" hole in the TB... jesus ... its not like I told you to shoot yourself

some people.. I swear ... I bet you didnt even use the search funtion... lazy
