    Angry speedo help please

    I have a 01 chevy 4X4 lifted with 285 75 16 tires on it. I regeared with 4.56 front and back. I plugged in the gear ratio and tire size but now I am getting a tire mismatch code also my ABS is reading 3 mph with the truck totally at a stand still. Did I miss something, can someone give me some advise?

    Post your tune. Sounds like you changed trans rev and you only need to change tire rev.
