The Edge Evolution CTS4 Gas combines powerful gas truck performance tuning with next-generation digital gauge monitoring in one advanced, easy-to-use device. Built for truck owners who want more from their daily driver, tow rig, or performance pickup, Evolution CTS4 delivers gains of up to 86 horsepower and 100 lb-ft of torque while improving throttle response, transmission shift strategies, power delivery, and overall drivability.* Pre-loaded, octane-specific performance tunes make it easy to optimize your truck for the way you drive. Select the 87 Octane tune for daily driving and economy, or step up to the 91 Octane tune for extreme performance and towing when you want maximum available power.* Improved throttle response provides a quicker connection between the pedal and engine, while vehicle-specific transmission tuning optimizes shift points, timing, shift feel, and power delivery. Evolution CTS4 supports many of America's most popular gas trucks, including select Ford F-150 EcoBoost and 5.0L V8, Chevrolet Silverado and GMC Sierra 5.3L and 6.2L V8, GM HD trucks with the 6.0L gas V8, and Ram HEMI applications through the 2014 model year.* Whether you're commuting, towing, hauling, or simply looking to wake up a stock truck, CTS4 delivers noticeable performance without requiring extensive mechanical modifications. More power is only part of the story.
