It includes five fully custom tunes that let you dial in your truck’s performance on your terms, without deleting emissions or compromising legality. Every tune is emissions intact and 50-state legal, so you stay compliant without giving up performance. The tunes cover everything from safe heavy towing to weekend power pulls, offering noticeable gains in throttle response, drivability, and overall feel. This setup is also a great way to avoid the headaches that come with over-tuning or running the wrong tune in the wrong scenario. With just a few taps on your smartphone using the EZ Lynk AutoAgent 2.0, your truck can go from work-ready to performance-tuned in minutes.

Five Custom Calibrations Engineered For Maximum Versatility

This 50 State Legal FIVE Tune Pack is built around DuramaxTuner’s proven ECM calibration strategy, offering more than 100 changes from stock per tune. You get five distinct power levels including Sport, Street, Light Tow, Heavy Tow, and Optimized Stock, all tailored to work safely with your emissions system. The Sport Tune pushes your LML to 532 horsepower and 1008 ft-lbs of torque, while the Street Tune offers up to +110 horsepower for daily use with improved throttle response and smoother acceleration. Towing-focused tunes feature built-in SMART EGT control and air-fuel ratio limits to manage heat and soot output under load. The Optimized Stock Tune provides minor refinements for troubleshooting or handing the truck off to less experienced drivers. All tunes are delivered through the EZ Lynk AutoAgent 2.0, a cloud-based platform that allows wireless flashing, data logging, and real-time diagnostics from your phone. This package also includes required EZ Lynk tokens and full support from a team that understands Duramax performance inside and out.
