    move your fail frequency up to over the point that your hitting.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    FWIW most NA LS1 fbodies have it set at 13500hz in stock form.

    Not really sure why GM sets it so low in stock form on boosted cobalts.

    Me either, it sets a 0171 with a CAI added and the fix is to raise it.
