The XRT Pro Street tuner is the perfect combination of high performance and value. The XRT Pro Street offers multiple power levels to exactly match your needs. Whether you simply want some extra power to pass when towing, or want an all-out high performance tune, the XRT Pro Street has you covered!
Default Power Levels (DPF Present Only)
Power levels are not currently shift-on-the-fly for the 2011 – 2013 6.6L LML Duramax. To adjust the Power Level, select Change Power Level from the Main Menu and follow the on-screen instructions (this may change in the future).
This option allows for the removal of the factory speed limiter. Most 6.6L LML Duramax trucks have a 98 MPH speed limiter from the factory. This option can only be changed during the Install Download process.
Transmission Reset / Relearn
The automatic transmission on the 2011 – 2013 6.6L LML Duramax has what is called Adaptive Memory and is constantly learning and adapting to different horsepower levels, temperatures, driving habits, etc. We highly recommend performing a Transmission Reset / Relearn procedure after installing H&S tuning to help the transmission perform correctly with the added horsepower. The transmission will eventually learn over time on its own, but the relearn procedure gives a good baseline for the adaptive learning and helps to speed up the learning process.
