Five Calibrations Engineered For Every Driving Scenario

DuramaxTuner’s Switch-On-The-Fly tuning for EZ Lynk AutoAgent 2.0 delivers fully custom calibrations for the 2013-2017 RAM 2500 and 3500 6.7L Cummins. The package includes five power levels, Optimized Stock, Heavy Tow, Light Tow, Street, and Sport, each dialed in with over 100 changes to the factory tune. Air-fuel ratio limits are built into every file to reduce soot, improve combustion, and protect emissions equipment, all while delivering noticeable gains in throttle response and torque. The SMART EGT control system monitors exhaust temperatures during tow-heavy scenarios and actively manages them to help avoid overheating or power loss. With EZ Lynk, you can monitor over 25 PIDs, stream data live, and even send logs directly to DuramaxTuner for real-time diagnostics. The interface also allows for code reading, troubleshooting, and easy updates through your iOS or Android device. This setup blends tuning flexibility with advanced engine protection, making it ideal for trucks that tow, daily drive, or demand performance without compromise.
