I got a 2012 WRX with the below listed mods. The stock throttle body hose literally disintegrated so I replaced it with a Grimmspeed Throttle Body hose. I had to take the TMIC off to fix it, knocked the BOV vacuum line off, replaced it. Ran fine. Not when ever I get into boost i can hear a loud wind rushing noise to overpowers the turbo spool. No CEL's. Obvious performance difference when boosting. Any idea's?
