Product Details

EvoHT2 20-23 GM Diesel Kit. It is strongly recommended that a battery charger be used during the ECM/TCM Unlock to ensure no voltage drop interrupts the process leaving an ECM in-operable. EvoHT2 with ECM/TCM Unlock for 2020-2023 GM L5P Duramax

Unlock the full potential of your 2017-2023 Chevy Silverado or GMC Sierra 6.6L L5P Duramax with the Edge EvoHT2 Handheld Tuner, the easy-to-use and budget-friendly flash tuner built for real-world performance.

The EvoHT2 comes preloaded with proven tunes designed specifically for towing, daily driving, fuel economy, and all-out performance, so you can select the calibration that best fits your needs. Just flash the ECM, unplug the device, and store it away, it's that simple.

To enable tuning on the latest L5P Duramax platform, the Edge Locksmith tool is required (included) to unlock the factory ECM and TCM. Once unlocked, the EvoHT2 gives you access to safe, emissions-compliant power gains that improve throttle response, drivability, and pulling strength.

Whether you're towing heavy trailers, commuting every day, or just want a stronger, more efficient truck, the EvoHT2 provides results you can feel immediately.

Beyond performance, the EvoHT2 also serves as a diagnostic tool, allowing you to quickly read and clear DTCs without an expensive shop visit.

Built on Edge Products' 20+ years of tuning expertise, the EvoHT2 is the perfect solution for Duramax owners who want reliable power, simple installation, and proven performance in an affordable handheld device.
