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 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. Note: Turning off Speed Limiter may result in a loss of cruise control, exhaust brake, and other functions
Transmission Reset / Relearn
The automatic transmission on the 2011 – 2012 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.
