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!

Much cheaper than paying for a speeding ticket! I have 37" tires on my Excursion and the Hypertech Calibrator was well worth the money. Calibrated the speedometer perfectly. Worth the purchase and very pleased. The calibration took about 15-20 minutes after the unit was updated.
