Featuring a sleek new look and state-of-the-art technology, the Juice with Attitude CTS2 sets the standard for power, control, and style. The Attitude CTS2 is an in-cabin controller that not only monitors vital vehicle parameters but allows you to shift-on-the-fly by controlling the Juice module for maximum control and power.

If you own a diesel truck and you're looking for complete control over your driving experience, look no further than the Juice with Attitude CTS2. With five (some applications have six with the hot unlock) different power levels and the ability to change power levels on the fly, advanced dynamic safety features for engine and transmission protection, and huge horsepower gains, the Juice with Attitude CTS2 delivers mild to wild, and everything in between. The Attitude CTS2 monitor stays mounted in the cab to monitor, in real time, everything a complete set of aftermarket gauges would monitor and more. The Juice with Attitude CTS2 delivers improved throttle response, overall drivability, safety, and power like nothing else in the industry. Whether you own a late model Ford, Dodge, or GM diesel, Edge has a complete lineup of products to suit your needs.
