    Default Need an original Operating System - 2010 4.8 4 speed

    A guy has asked me to put his truck to stock, he's not sure who tuned his truck before but he doesn't like it. It's a 2010 4.8 4 Speed

    Engine Operating System 12636005
    Transmission Operating System 24243357

    Stock Tune Files doesn't seem to be working... If anyone here could help me out or point me in the right direction that would be great!

    Here are the files I'm working with.

    Thanks.
