1994 - 2003 Ford F-Series Power Stroke 7.3L. This has never been used. The Edge Evolution programmer is designed to increase your vehicle's power output. Key Features: 3 Seperate Performance Programs. Quick and Easy Installation. Additional 100 horsepower and 200 foot-pounds of torque to make sure your truck can go where it needs to go, whether driving, towing, or racing. Increases Fuel Economy. Displays 0-60 and quarter mile times. The Evolution is also a powerful diagnostic tool. Not only can you view trouble codes that your vehicle may be displaying-which allows you to fix them, but you can turn off that "Check Engine" light when the program has been addressed. The small lightweight design allows personalized control with the touch of a botton. With a backlit LCD screen, seeing and reading codes is now a simple process. The unit not only displays codes but also displays a description of what these codes mean, which eliminates copying the code down and then finding the manual to look them up. Level 0: Stock.
