The pack includes a Sport, Street, Light Tow, Heavy Tow, and Optimized Stock tune, all designed to safely increase power and torque without putting stress on your engine or emissions components. Built-in SMART EGT control actively manages exhaust temperatures during demanding conditions like towing or high-speed driving.
