    Default Gdp

    A few months ago, I bought a GDP from eBay. I'm concerned that I did the wrong thing. I have pulled the radio and OnStar fuses and plugged it in. I get codes 0280 and 0281. My connection is good. What am I doing or not doing correctly?
    Thanks

    Contact GDP.........the issues can be resolved by contacting the tuner you purchased from, EFI-Live does not indirectly support the tuners customers usually

    Tuner of many, many Duramax and Cummins Diesels.
