Built For Safety Tuning Precision And Smart Performance

This FIVE Tune Pack offers more than just power – it delivers precise control backed by over 100+ custom calibration changes from stock. Each tune is emissions intact and 50 state legal, with safeguards like SMART EGT Control and built-in air-fuel ratio limits to reduce soot production and keep temps in check under load. Whether you're using the Light Tow tune for small trailers or the Heavy Tow for full GVW loads, your engine and emissions system stay protected. The EZ Lynk AutoAgent 2.0 makes diagnostics and updates easy, giving you wireless control of your tune files and access to real-time data logging from your phone. Even the throttle response and shift strategy are carefully calibrated for a smoother and more responsive drive, no matter which tune you're running. With the included Optimized Stock option, you can always revert to a slightly adjusted factory baseline. This tuning solution gives you professional-grade customization without compromising the drivability, safety, or emissions compliance of your truck.
