Unlock The Full Potential Of Your Duramax

If you’ve been craving more power, better drivability, and full control of your 2014 Duramax without compromising emissions equipment, this EZ Lynk FIVE Tune Pack delivers it all. You’re getting five custom tunes that can take your truck from smooth daily driving to all-out performance, depending on what your day demands. Whether you're commuting, hauling, or just having fun on the open road, this setup gives you power when you need it and restraint when you don't. With tunes ranging from Optimized Stock to Sport, you can enjoy better throttle response, improved acceleration, and even safer towing capabilities. The Street Tune alone will wake up your truck and make it feel lighter on its feet, while the Heavy Tow tune keeps EGTs in check when you're pulling serious weight. Backed by DuramaxTuner’s legendary customer support, this package includes the EZ Lynk AutoAgent 2.0, so flashing your tunes and monitoring data is as easy as opening an app on your phone. If you want a legal, reliable way to boost performance without headaches, this combo was built for you.

Engineered Tuning That Works With Your Truck

This 50 State Legal FIVE Tune Pack is built to work in perfect harmony with your emissions systems while still delivering up to +135 RWHP and +243 ft-lbs of torque. With over 100 unique calibration changes, each tune is designed to manage airflow, fuel delivery, and boost more efficiently than stock, reducing soot output while enhancing performance. The SMART EGT Control built into the Light and Heavy Tow tunes automatically regulates exhaust temps, keeping your truck safe under load. This setup also includes transmission (TCM) tuning capability, which means firmer shifts, better torque converter lockup, and more usable power across the RPM range. The EZ Lynk AutoAgent 2.0 simplifies tuning with wireless setup, real-time data logging, and diagnostic features right from your smartphone. Whether you're running larger tires, a modified turbo, or a built transmission, this system helps keep your engine and transmission operating in sync. It’s a comprehensive, emissions-compliant tuning solution that’s easy to install and built to handle real-world demands.
