    C5 Magnacharger Fuel Trim issue only Bank 2

    I have a problem with a Magnacharged C5 man. trans.
    car runs nice and makes good power but fuel trim on bank 2 freaks out +20% always on 2500-2700 rpm.
    the fuel trim issue is not in relation with MAF signal. its always on the same rpm range in different gears and different MAF HZ readings.
    I changed the fuel injectors on bank 2 but still the same.

    can someone please have a look

    Thanks

    Sounds like it could be a misfire on that bank.
