GM Duramax LM2 3.0L Delete Tune (2020-2022)

Take your driving experience to the next level with the Delete Tune File for the 2020-2022 GMC Sierra and Chevrolet Silverado LM2 3.0L Duramax Engines. This tuning solution is a must-have for diesel enthusiasts who demand more from their vehicles.

Why Choose the Delete Tune File?

The Delete Tune File delivers numerous benefits:

• Enhanced Performance: Expect a noticeable increase in horsepower, torque, and throttle response, giving your truck superior power and acceleration across all RPM ranges.
• Improved Fuel Efficiency: Optimize fuel delivery and combustion for more miles per gallon without sacrificing performance.
• Emissions Optimization: Streamline exhaust flow by removing restrictive components, reducing backpressure, and improving engine longevity.
• Custom Tailored Tunes: Unlike most other LM2 tunes that are based on a single pre-made file, our tunes are manually created using your specific stock file.  This ensures all software segments are unchanged so you won't have any issues such as fan issues, cruise control issues, error codes or dash messages.  We have not found anyone else offering this service.
