The original X-Tuner has been a favorite with diesel enthusiasts for years—and now BD has introduced its successor: The Ultra X-Tuner. As the name would imply, the Ultra X-Tuner offers even more performance and capabilities than its predecessor. Selectable power gains of 30 hp Horse Power to 140 hp Horse Power are possible (depending on application), along with improved fuel economy and better driveability 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, recalibrate 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 (most applications).

The Ultra X-Tuner is BD’s most advanced programmer yet.
