I installed my hyperflow tmic while ago and then cleaned the inside of my forge bov, I was wondering what could be making the whistling noise upon boost? could it be my bov or the tmic, maybe a hose not tight or something. any advice would help. oh yeah, i'm still using my stock air splitter which doesn't form a seal too well. thanks
You have a leak somewhere, as you've figured out. Maybe you didn't tighten the y-pipe or BOV down, or maybe you bungled up a gasket somewhere.
it sounds hillarious, just making sure it was nothing serious. I like to screw things up ya know. thanks i'll check the pipes
i had that SAME noise yesterday when i installed mine... if u used 1 gasket for the BOV, try using 2... that fixed my problem
