Give your 2001–2016 Chevy Silverado or GMC Sierra Duramax the ultimate performance upgrade with the Edge Evolution CTS3, a tuner and monitor that redefines what your truck is capable of. Engineered for the 6.6L Duramax platform, the CTS3 delivers proven horsepower and torque gains that make towing, hauling, and daily driving more powerful and efficient. Suporting LB7, LLY, LBZ, LMM and LML trucks you can see gains of up to +120 horsepower and +200 lb-ft of torque. These calibrations optimize drivability by improving throttle response, reducing downshifting under load, and giving you the confidence to handle heavy trailers or steep grades with ease.
