    Default 03 Silverado SS stock tune needed

    I am in search of a 03 Silverado SS stock tune. Had a hypertech or something and the programmer was lost and never taken off. Trying to find a stock tune to work with before the truck comes in so I have a good start on it. But anything for a truck like that would be great if anyone has something thanks.

    I've looked but I haven't found a 6.0l with a 4l65e tho. It seems to be a bit hard to find.

    If you are expecting the transmission type to be indicated as "4L65" when you open the tune - it never will.

    Just look for an LQ9 engine - in a Silverado, that denotes an SS model.
