Installed larger tires on my 2010 Toyota Tundra after doing so traction control was off badly when acelerating at speed it would imeditly kick in. After installing all is correct now and I'm getting 1.5 mpg better on gas mileage. 5 stars

Bought it cause I put 35's on my Tundra and I was about 5mph off comparing to GPS. Also noticed shift points were off along with gas mileage. This calibrator not only allows you to fine tune the speedometer but it also brings the shift points back to factory settings. I am now back to 18+mpg on highway and 13-14 aound town and I am heavy on the right foot. Easy install, just make sure to zip tie to prevent rattles behind the dash. Highly recommend.

I'm slightly off but I need to readjust it thats all. Corrected my shift points and installation was simple. Super easy to use and program. Instructions are slightly vague but its not too hard to figure out.

The product arrived quickly and was exactly as advertised. Instructions were a little off, but useful and it worked perfect on the first try. Reading within 1MPH of two GPS units. Only took about 40 minutes to install. Very impressed so far.

The product works as described but I had to search the web to find installation instructions. NONE were included in the box. You may want to measure your tire height rather than just enter the size to get an accurate adjustment. I recommend leaving the usb cable connected to the unit, coiled under the dash so you don't have to take the dash apart to make tweaks to the settings.

It only took 2 minutes to program, 30 minutes to install and we were right on target. Checked speedometer VS GPS speed app and we were right on the money. I have Factory Toyota Software which could not adjust for tire size, This Can!

I had it installed by a professional mechanic. After having it on, the quality of the ride is so much better, especially since I'm running 37" tires. Highly recommended.
