As the title says, the Hypertech Speedometer Calibrator does just what it says it does. It was extremely easy to install, and walks the user through each step. The quality seems to be very good, although the value/price seems steep considering that it only does one thing. OK, it also reads the DTC's but that's a necessary part of the function of changing the speedo calibration anyway. Appearance? 3-Stars because it's just another black box.
