I watched a video on you tube on installation of my particular truck and installed in 30 minutes.Easy to program correction module from my lap top. Make sure you drive it to check corrected speed with a GPS. The tire sizes I input into the module over corrected speed, but it was easy to adjust.I'm very Happy with this HyperTech product. Now. my speedometer is within 1/2 mph of GPS speed

This is a relatively easy install. I used it on my 21 F150. You have to pull a lot of the dash part. That was a little stressful even though I've done these things before. You will need a trim tool. It went well and it works great. I just hate tearing new trucks apart. had to be done though for the bigger tires overall, it is really great product

Easy install and works great

easy install and programing. no need for GPS anymore. I used this product because it was the only one that would go over 37"" tires. That does not work very well for 44"" tires.

The product arrived quickly and was easy to use. Installation was simple and now my 2017 f250 is reading the correct speed with 37"" tires

Used to correct speedometer for 37"" tires. Was a little hesitant to pull the cluster on my own but the video made it easy.

Easy to install. Works perfectly on a 2017 F250 Lariat 6.7 diesel.

Great product!Used on 2017 Ford F-350 to adjust my MPH on speedometer to match tires
