    NO BOOST 2011 WRX?!??!?!?

    Today i was driving my 2011 wrx sedan, i was driving hard and everything was okay and all of a sudden after i turned a corner i lose all boost and for some reason there is little to no noise coming out of my exhaust. No exhaust pressure. My COBB boost controller is reading around 2-3 psi at around 4000rpm.

    My mods: Cobb Air intake with a stage 1 tune (91 octane) Invidia Q300 Catback

    Also: A bracket broke on one of my cats causing it to rattle, i didnt fix it could've broke on the inside?????

    Tried Re-Mapping, didn't work, No check engine.

    Right before 100k KMS so I'm still covered under warranty

    What is your DAM at?

    A rattling bracket technically could cause your ECU to go into limp mode and pull boost if it's reading enough false knock.

    Do you have a check engine light on with flashing lights?

    When I got my po244 overbooost code, I was under heavy acceleration up hill when the fuel cut and lost power.

    If not, check your vacuum lines.
