What is a Cummins Tuner?

A Cummins tuner is a high-tech device that reprograms your truck's Engine Control Unit (ECU) for optimal performance.

Unlike stock settings bogged down by emissions restrictions, our Cummins delete tuners—such as the best delete tuner for 5.9L/6.7 Cummins—disable components like the DPF, EGR, and DEF.

This 5.9L/6.7 Cummins tuner with deletes boosts horsepower, torque, and fuel economy while eliminating pesky regen cycles and error codes.

Perfect for 2007.5-2021 Ram 2500/3500 models, including the 2018 Ram Cummins tuner or 2013 6.7 Cummins tuner setups.

How to Choose the Right Cummins Tuner

Pick smart: Pre-2019 6.7L Cummins (with CP4 pumps) differ from 2019+ models (CP3 upgrades and ECM changes), so match your year—such as a 2008 6.7 Cummins delete tuner or a 2018 6.7 Cummins tuner.

Opt for off-road Cummins delete tunes if emissions aren't a concern, or smog-legal for California compliance.

The Cummins tunes keep it safe for daily drives; race tunes demand modifications for maximum horsepower.
