Description
Edge has changed the game—again. Meet the EvoHT2 with ECM/TCM Unlock, the industry’s first true in-vehicle flash tuning solution for the 2020–2023 GM 6.6L L5P Duramax. No more ECM swaps, no more shipping parts, and no more down time. The EvoHT2 includes everything you need to unlock both the ECM and TCM right from your truck using the included Locksmith tool and cables.
Now featuring full 10-speed Allison transmission tuning, this package delivers powerful performance and drivability improvements for towing, daily driving, or all-out performance. Gain up to 125 HP and 275 lb-ft of torque with four preloaded tunes, and fine-tune your driving experience with pedal sensitivity control, speedometer recalibration, idle control, and more.
Best of all, this system is simple, effective, and costs less than half of competitive ECM flash tuning solutions—with no extra tuning credits, fees, or hidden costs.
Important: Unlock is VIN-locked and non-reversible. Once unlocked, the device becomes non-returnable.
