It does everything that I needed it to.

With having oversized tires on my truck when I bought it, the speedometer was off by enough to be more than simply annoying. Once I got the unit, I plugged it into my computer and it updated. Once that was completed, I had a few options to get my speedometer where it needed to be. I elected to use the tire size option, where I put in the OEM tire size in one box and my current tire size in another box. I hooked it up to the truck which took about 20 minutes and took her for a test drive. I couldn't be happier as everything was spot on after installation. Thank you Rough Country!!
Must have if you install bigger tires.

Works great on my 2019 Chevrolet Colorado ZR2. Easy to program and took less then 15 to install. Speedometer and transmission shift points greatly improved after installing larger tires.
Follow the instructions and it works great

Just got this for my 2018 Colorado after lifting it and adding bigger tires. So, package arrived simply download the program from Rough Country, enter your original tire size, enter the new tire size then select program...install was just as easy just follow the instructions. Worked perfectly! Speedometer is now spot on with gps speed.
