Turn Your Cummins Into A Whole New Truck

If you're looking for real power gains without tearing into your emissions system, the DuramaxTuner Switch on the Fly Tune with EZ Lynk AutoAgent 2.0 is one of the smartest upgrades you can make. This system gives your 2018 6.7L Cummins the ability to instantly switch between five custom tunes while you're driving, so whether you're towing a heavy load or looking for max throttle response on the highway, your power is always right where you need it. With tunes that add up to 100 rear-wheel horsepower and 180 ft-lbs of torque, it completely transforms how your truck accelerates, pulls, and responds. The included EZ Lynk AutoAgent 2.0 hardware connects through your phone, letting you monitor live data, clear codes, and update tunes without touching a laptop. Each tune is carefully calibrated to work with your emissions equipment intact, so there’s no need to delete or risk reliability. You’ll get improved throttle sensitivity, reduced soot output, and a noticeable drop in turbo lag. Whether you daily drive, tow, or just want your Cummins to feel more alive, this is an upgrade that delivers every time you press the pedal.

Emissions Safe Power With Smart Calibration Control

This tuning package is built specifically for 2018 RAM 2500 and 3500 trucks running the 6.7L Cummins with emissions equipment still in place. Using the EZ Lynk AutoAgent 2.0, each of the five included custom tunes can be switched on the fly using a connected smartphone, offering real-time flexibility for driving conditions. The Sport and Street tunes deliver up to 100 RWHP and 180 ft-lbs, while the Light and Heavy Tow tunes are calibrated with built-in SMART EGT controls and air-fuel ratio limits to keep exhaust temps in check. Optimized Stock is also included, giving you a factory-like tune with minor refinements for troubleshooting or valet use. The EZ Lynk interface supports up to three fully customizable gauge screens, live data logging, and firmware updates without needing a PC. This system does not require any wiring modifications or cutting into factory harnesses, which makes installation straightforward. It's a clean, emissions-legal tuning solution that enhances drivability, protects your drivetrain, and helps you get the most out of your Cummins.
