While many in the market thought it couldn't be done, we're excited to introduce the Evolution CTS3 for 2020-2023 6.6 Gas GM trucks, featuring in-vehicle ECM unlocking capabilities! This cutting-edge in-cabin device is your all-in-one solution, allowing you to unlock your ECM, flash performance calibrations to both the ECM and TCM, and monitor everything happening under the hood through its state-of-the-art touchscreen display.
This revolutionary process transforms how you tune your 6.6L L8T gas truck, paving the way for the future with even more features. It's designed to save you both time and money when modifying your truck. With the Evolution CTS3, you can expect noticeable power gains of up to 28hp and 50tq, along with improved throttle response, better fuel economy, and complete control over your driving experience. You’ll love the 'Remember Last Setting' feature, which ensures your truck recalls your Drive Mode settings every time you start it. Plus, you can calibrate for larger tires and adjust your top speed limiter. It’s the perfect tuning option for anyone who wants everything in one device, featuring an easy-to-use touchscreen interface, stunning visuals, and pre-loaded tunes tailored to meet every owner's specific needs. Whether you're aiming to boost your daily driving mileage, enhance your towing performance, or just enjoy some spirited driving with that powerful V8, the Evolution CTS3 has got you covered.
To unlock and tune your vehicle, you will need a PC and our downloadable Update Agent software.
Please note that this device can unlock and tune only one vehicle. Once the ECM is unlocked and flashed, you can revert the flash to factory settings, but the unlock process cannot be undone. If the VIN lock and ECM unlock have been completed, the device is non-returnable.
