Custom Calibrations That Adapt To Your Driving Needs

This Switch-On-The-Fly tuning package is built specifically for the 2018 RAM 2500 and 3500 6.7L Cummins using the EZ Lynk AutoAgent 2.0 platform. It comes preloaded with five unique tunes, Optimized Stock, Heavy Tow, Light Tow, Street, and Sport, each tailored with over 100 changes to the stock calibration. These tunes adjust throttle response, fueling, boost control, torque management, shift behavior, and more, all while keeping emissions systems intact and functional. SMART EGT control is built into the tow tunes to help manage exhaust gas temperatures under load, giving you more confidence while pulling uphill or in hotter climates. Air-fuel ratio limits help reduce soot output and keep your truck running clean and efficient. Using the EZ Lynk app, you can switch between power levels on the fly, view real-time data, read and clear trouble codes, and send logs directly to your tuner if needed. This setup offers a seamless blend of performance and usability, giving you tuning flexibility without the hassle of constant reprogramming. It’s the ideal solution for drivers who expect more from their truck without giving up factory reliability.
