    replace the ecm with one that isn't tunerlocked.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    piggybacking this, I am having the same issue. Tune is from livernois, which I know locks their stuff, and when i talked to the guys at vortech who was setting it up with HP Tuners said they had no issues.
