The Edge Evolution CTS3 is the ultimate performance upgrade for 2017–2023 Chevy Silverado and GMC Sierra 6.6L L5P Duramax trucks, combining powerful flash tuning with the industry’s best in-cab monitor. This all-in-one device includes the revolutionary Edge Locksmith tool, which unlocks the ECM and TCM through the OBD-II port, giving you access to preloaded emissions-friendly calibrations designed for daily driving, towing, fuel economy, and performance. Simply flash your truck, unplug the tool, and enjoy safe, reliable power gains you can feel every time you drive.
The CTS3’s 5-inch high-resolution touchscreen provides unmatched visibility and control, letting you track critical parameters, log performance data, and customize gauge layouts. Beyond tuning, the Evolution CTS3 gives you access to an impressive range of adjustable features including tire size recalibration, speed limiter adjustment, remembering tow/haul and exhaust brake settings, and more. With its intuitive swipe interface, built-in diagnostics, and Wi-Fi update capability, the CTS3 sets the standard for modern diesel tuning and monitoring.
The Evolution CTS3 also made history as the first to market with 10-speed transmission tuning support, unlocking smoother, stronger shifting on 2020+ L5P trucks. Now, it’s once again leading the way as the first to offer direct OBD-II flash tuning for 2017–2019 6-speed transmissions, eliminating the need for bench flashing or third-party hardware.
Backed by Edge’s 20+ years of diesel tuning expertise, the Evolution CTS3 for L5P Duramax is the go-to choice for owners who want big power gains, better fuel economy, imrpoved drivability while towing and advanced features, and the most powerful monitor in the industry, all in one sleek package.
