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

Easy Install

I was uncomfortable about tearing apart the dash on my 2014 tundra, but the instructions were legit. Took about 30 mins. I have a 6 inch lift with 35 inch tires. The first attempt i plugged in 35 inch tires, but the speedo was still off, so I measured them and they were actually 34.5. Plugged that in and now speedo is right on the money. As others have said I left the usb coiled up under the steering column, to easily access it with laptop anytime i need recalibrate.

Went from Stock to 35s. Really easy to put on, truck shifts smoother, speed is perfectly on with two GPS and I also had my wife drive her car next to me and tell me how fast she was going. I actually gained 1.5 MPG, don't know how or why but it did. Tucks right behind the dash and I left the usb in it so I could change it if need be without taking the dash apart again

Super simple
