As the title states I just installed my FMS FMIC on my 2013 wrx. Everything fits well and looks good. Took the car out for a quick drive to make sure no leaks and I blew the stock throttle body pipe off fairly quickly. Threw that back on and made sure to snug it alot tighter then it was before. Everything runs fine now but there is a faint whistle sound like a leak. My question is for anyone who has this FMIC or helped someone install one. Did you do anything to the stock throttle body pipe such as I read that you need to take the end caps off or something along those lines. I already ordered a Gimmick Motorsports throttle body pipe but that wont be in for a week. Im just trying to do something to stop the whistle sound and something to hold me over until the new one comes in. Is there anything I could do to check for leaks in the piping along the couplings.
