{"product_id":"evolution-cts4-17-19-gm-l5p-diesel-with-locksmith","title":"Evolution CTS4 17-19 GM L5P Diesel with Locksmith","description":"The Edge Evolution CTS4 for 2017–2019 Chevy Silverado HD and GMC Sierra HD 6.6L L5P Duramax combines powerful diesel performance tuning, transmission tuning, and next-generation digital monitoring in one easy-to-use device. Designed for Duramax owners who want more from their daily driver or tow rig, Evolution CTS4 delivers substantial horsepower and torque gains with improved throttle response, stronger acceleration, optimized shifting, and better overall drivability. The included Edge Locksmith tool unlocks the factory ECM and TCM, giving you access to pre-loaded, emissions-friendly calibrations designed for Towing, Economy, and Extreme performance. Choose the tune that matches how you use your L5P Duramax, whether you're commuting, pulling a heavy trailer, or looking for maximum available performance. Adjustable features also include supported options such as tire size recalibration, speed limiter adjustment, and remembering Tow\/Haul and exhaust brake settings. For 2017–2019 L5P trucks, Evolution CTS4 offers direct OBD-II flash tuning for the factory 6-speed transmission, eliminating the need for traditional bench flashing or additional third-party tuning hardware. Optimized transmission strategies improve shift timing, shift feel, power delivery, and drivability to help your Duramax perform better whether the truck is empty or working hard with a trailer behind it. The CTS4 diesel tuner and monitor lets you keep an eye on supported engine, drivetrain, temperature, pressure, and other critical vehicle parameters through customizable digital gauges. Set custom alerts and warnings, record vehicle data with built-in data logging, and read and clear supported diagnostic trouble codes directly from the device. More power. Better response. Smarter monitoring. Take Control with Evolution CTS4. *A PC and Edge's downloadable Update Agent software are required to complete the tuning process. **Device can unlock and tune only one vehicle. Once the ECM is unlocked and flashed, the vehicle can be returned to the factory calibration, but the unlock process cannot be reversed. Once VIN lock and ECM unlock have been completed, the device is non-returnable.","brand":"Edge Products","offers":[{"title":"Default Title","offer_id":51041929232642,"sku":"BKDQ_85500-262","price":929.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/ec5083fa7c9f29119720b7c6291d30d6a68baff0_2e2a8aaa-26fc-40b2-855b-a15ddc36205b.jpg?v=1794547399","url":"https:\/\/www.lethalperformance.com\/products\/evolution-cts4-17-19-gm-l5p-diesel-with-locksmith","provider":"Lethal Performance","version":"1.0","type":"link"}
