    This is all trial and error, I programmed a 2007 Duramax LMM with 325/60/20's tires which = 35.35" tire height...I learned that the ECM didn't like to see anything over 35" so Ive been using a tire height of 315/60/20 which = 34.88" tire height and Revs are 578.18 per mile
    The ABS & Brake lights went away and the speedo is off by 1.5 mph sometimes 2 mph on the freeway.....Hope this helps

    Well i have been talking to a few other people and trying different things. I have been from 605 to 620 to 640 and now back to stock tires size and still having problems. I also pulled the abs sensors and checked them and couldnt find anything wrong. There is some more updates on my dieselplace thread if you want some more info

    Man, I don't know why it won't work for you...You've been all over the place with the Revs, maybe something else is keeping it from working right...........
