As the name would imply, the Ultra X-Tuner offers even more performance and capabilities than its predecessor. Select-able power gains of 30 hp to 140 hp are possible , along with improved fuel economy and better drive-ability overall. As with the original X-Tuner, the Ultra X-Tuner simply plugs into the vehicle?s OBD II port, and allows you to read diagnostic codes, re-calibrate the speedometer for larger tires, and raise/eliminate the vehicle?s top speed limiter. Plus, you can download the latest calibrations as well as an available data acquisition package from the Internet
