The description was lacking a bit so I wasn't sure if it would work on my 2023 Silverado. Found out the hard way in won't

Super easy to install. Takes longer to program than actually install on your vehicle. Checked it with GPS. I was off 4 mph before. Dead on now! You gotta have this if you need to recalibrate your speedometer.

The program is super simple to use and fast to program

I added tires to my truck that are 3.5"" bigger diameter than stock. I bought this calibration device to fix my speedometer. Took 2 minutes to calibrate online. Took 2 minutes to install. Works perfect. I used GPS on my phone to verify my truck speed, and it matches the speedometer now.

Simple to program and install. Done exactly advertised corrected my speedometer when I changed Tire size. Must have if you have a 2019 or newer GM vehicle. The factory locked out the ability to even have the dealer change your tire size.

I have a 2021 Silverado Z71 I lifted it and put bigger tires and speedometer was off. This product was easy to install and program highly recommended.

Speedometer correction for slightly larger tires installed on 2019 GMC CANYON

This literally took 5 min to download and update, and apply vehicle settings. Though you need to be sure to input the actual manufacturers specific tire diameters from the manufacturer web sites

Works as described and easy to set up
