Product Info

Product Info

2020-2025 Chevy LM2 3.0L HP Tuner with Tunes pairs the listed tuning device with the applicable tune package and any required access items shown in the selected options.

Confirm the listed year, make, model, engine, and any truck-specific configuration before purchasing. Review the available ECM, Tuning Levels selections before ordering. The exact contents and fitment depend on the options selected on this product page.

How to Choose Your Options

  • ECM selection: E46 and E66 are different ECM/controller choices. Select the controller ID actually installed in the truck rather than choosing by model year alone, because the listed year ranges overlap.
  • Tune level: Level 1, Level 2, and Level 3 select the calibration level supplied for this exact ECM and truck. The source product data does not assign universal horsepower numbers to these level names, so they should not be treated as interchangeable power ratings across different controllers.
