    High speed write to 2005 Duramax

    I have been working with a 2005 Duramax and encountered the problem of failed read when set to high speed. I was able to succesfully complete it in half an hour on low speed. Today I reflashed it at low speed as well without issue. Can I do a high speed write to this vehicle? Didnt want to risk having a write failure so didnt try.

    High speed writes shouldn't be an issue.
    It doesn't have to be perfect, it just needs to be done in two weeks...
