Worked as advertised. My calculations say my tires are 34". With truck weight they measure about 33.5. That is the number I used and it put GPS spot on. Truck seems to be shifting back into 4 cal mode more regularly now helping to boast mpg. Worth the investment.

Put 3.73 gears in 2010 Siverado. Dealer could not calibrate speedometer. Did myself with Hypertech Speedometer Calibrator. Well pleased.

I initially set the unit for 34" tires, the diameter of my Toyo ATIIs in 295 60r20, the speedometer was actually a couple mph over. After some downward-tweaking for tire inflation level, I setting the unit to correct for 32.75 inch tires got my speedometer accurate to within less than 0.5mph error compared to Garmin GPS. Keep in mind that actual tire diameter is dependent on how many psi you are running, so getting things right on the money may take some tweaking.

Started off with the Hypertech inline speedo calculator,it recalculated speedo,but ABS had problem with incorrect speed,call tech with problem,they said I needed the Reprogrammer732501,after uploading program for my truck,it wont communicate,called Hypertech,it isn't compatible with 4.3 V-6,something I stated when I called you guys about because it wasn't listed as an option in the catalogue,but your salesman said that it would work,and that you needed to update the listing,but it wont work

2014 GMC Sierra 1500. Fairly easy installation. Manual days you need to remove several fuses, but this is not necessary. Just make sure headlights are off, radio is off, and nothing is plugged into DC outlets. Did what it said!

Bought an 08 Chevy 2500 with 18" wheels. No help from dealer on speedometer correction. Found Hypertech on internet and was somewhat hesitant about ordering it. Got it anyway, programmed it to my vehicle, measured wheel as told to do and plugged the programmer in. In about 2 minutes DONE. Speedometer is now "RIGHT ON". Great product.

This was pretty easy to install once I got the update put on the programmer. I had some issues with shifting prior to installing and had to return to stock mode. It was quick and easy. Got my truck back and reinstalled.
