My 09 Tacoma was a full five MPH off at highway speeds. I kept getting the same aggravating excuse. It's within factory specs.Checking online, I found this was a common problem. With the Hypertech Speedometer Calibrator I was able to program in different axle gearing to dial the speedometer right in to where it should be. I wish I had known about this product sooner. Rob.
