Unlock The Full Potential Of Your Cummins With Seamless Power Control

If you’ve ever wished you could adjust your truck’s power on the fly without stopping, plugging in a tool, or rewriting files every time, this Switch On The Fly tuning package delivers exactly that kind of freedom. It gives you five custom tunes that you can cycle through while driving, letting you jump from heavy tow mode to a sport-ready power level with nothing more than a quick switch. The difference in throttle response and overall drivability is immediately noticeable, making your 2013–2017 Cummins feel lighter, stronger, and far more responsive. Each tune is designed to be emissions intact, which means you don’t have to touch your factory emissions equipment to enjoy real performance gains. Whether you want something smooth and reliable for daily use or a tune that makes the truck come alive for spirited driving, this setup covers every situation. It’s backed by more than a decade of custom tuning experience, so you’re getting calibrations that are proven on real trucks, not generic files. For anyone who wants flexibility, reliability, and a serious improvement in how their Ram drives, this tuning package changes the entire experience behind the wheel.

Precision Built Calibrations Tailored To The 6.7L Cummins Platform

DuramaxTuner’s Switch On The Fly system provides a complete calibration overhaul designed specifically for the operating characteristics of the 6.7L Cummins engine. Each of the five included tunes modifies more than one hundred parameters within the ECM, giving you optimized fueling, upgraded torque management, and refined throttle mapping for consistent and predictable performance. The sport setting can deliver gains of up to 130 rear wheel horsepower and 234 foot pounds of torque, while the tow oriented files rely on air fuel ratio limits and SMART EGT control to keep exhaust temperatures in check during demanding pulls. The tuned files retain full turbo brake functionality and avoid any requirement to splice into wiring or trick sensors, ensuring a clean and dependable setup. This tuning also pairs exceptionally well with transmission tuning for the 68RFE, allowing higher line pressure, better clutch holding capacity, and improved shift timing to match the added torque. Trucks equipped with the ZF6 manual or the Aisin transmission also benefit from tailored engine calibrations that account for how those drivetrains operate. With proper tuning structure and clear safeguards built in, this package gives the Cummins the powerband it always should have had while maintaining reliability for daily driving or towing.
