ok, i think i may possibly have a problem with the new throttle body/upper plenum i just installed.. its a accufab 75mm throttle body with a C&L upper plenum. ok.... when im accelerating i hear a whistle type noise coming from under the hood... i dont know what the noise is... is it from just having much more airflow or is the noise sound from not having the tb or plenum on tight enough or not having the exhuast thing on tight enough to the plenum.. please help me with this! it does sound cool though, sounds like a supercharger whining up.

lol, calm down dude. It's completely normal, it's just the increased airflow. Mine does it too.

ok... i didnt notice the noise till like 3 days after i had the plenum/tb installed. so i was wonderin if something was wrong or not. now i just need exhuast and my motor will be flowin pretty good.

DOnt worry about it bromellion, its one of the beauties of the setup ur running, (ive got that stuff too), if u really want a sick sound, pop the hood, and rev ur engine from the throttle body, u can really hear it then!!
