2001-2007 6.6L GM Duramax LB7 / LLY / LBZ
BD-Power Ultra X-Tuner
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 up to 85 horsepower, 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.
