• Extreme Tune (150hp/350tq) can produce well over 500 rear-wheel horsepower for an adrenaline rush and sports car acceleration you didn't think possible from a 3/4-ton truck
• Calibrate speedometer for larger tires on a lifted truck, offering an accurate MPH, odometer, and transmission shift strategy
• Remember Last Button Setting feature allows the Tow/Haul, Exhaust Brake, and Grade Braking settings to remain enabled on every key-cycle. Super convenient while towing
