    4l80e truck tune

    anyone have the latest gm 4l80e stock tune for a truck? i'm assuming the truck shift points etc are the same on trucks with the same trans? i have a express van 1 ton, i would imagine a 2500 suburban would have the same settings

    Different gearing and tire size are going to scale the transmission settings differently.
