2011-2016 LML Custom Tunes

Our calibrations are 100% custom-written and tailored specifically to your truck's build and modifications. Every tune is designed to provide the best balance of drivability, performance, and reliability. Lifetime tuning packages include unlimited revisions as your setup evolves. We support tuning for devices such as EZ Lynk and EFI Live.

Custom TCM tuning is available for an additional $200.

For LML Duramax trucks, we do not recommend or support multi-file tune switching. Instead, we focus on creating a single, properly calibrated tune that delivers smooth drivability, consistent power, and long-term reliability without the compromises often associated with stacked or switchable tune files.

We also offer novelty calibrations, including limiter, smoke, and lope tunes. While these tunes are available upon request, they are intended for off-road or exhibition use only and can significantly increase wear and stress on engine and drivetrain components. Because of the increased risk, a signed liability waiver is required before these calibrations will be provided. By requesting these tunes, you acknowledge the potential for accelerated component wear and agree that we are not responsible for any damage resulting from their use.
