Awesome product!!! Great step by step instructions. Had 0 problems with the installation, it took about 45 minutes from start to finish. I would recommend you measure your tire to get the exact size. I upgraded to a 22in wheel with 35s and programmed 35s first and it was still off 2 MPH. Once I measured and saw that it was really a 34, I programmed that in and it was perfect. Much smoother shifting too. I also noticed a 2mpg gain too!!! This is a must if you have a lift Tundra with 35s or larger
