hey all. i have a 2003 gmc sierra with a 5.3ls and a 4l60e 4x4. im in the process of doing a swap to 4l80e. im having a hard time finding an xdf that isnt locked or one that is already what i need. does anyone have a prebuilt file or an unlocked xdf for this? been looking for days with no luck. its a 1mb ecu. i also have zero clue how to do a segment swap and im having trouble finding resources to learn. thanks for any help.
