6.7 Cummins Delete Tuner

Why Does Your 6.7L Cummins Need a 6.7 Cummins Tuner?

Stock Tuning Limits the 6.7 Cummins Tuner Removes

The factory calibration on a 6.7L Cummins is written around emissions targets, not torque. A 6.7 Cummins tuner strips those limits so the injection pump and turbos work together instead of fighting a regen schedule.

Regen Cycles the 6.7 Cummins Tuner Eliminates

Every forced regen burns extra fuel and soaks the exhaust in heat. By running delete tunes, a 6.7 Cummins tuner ends the cycle and keeps exhaust gas temps in a safe band on long pulls.

EGT Control With a 6.7 Cummins Tuner

Proper timing and fueling from a 6.7 Cummins tuner drops peak exhaust gas temps under load, which protects the pistons and the turbo during sustained towing.

What Can a 6.7 Cummins Tuner Solve?

Restore Horsepower With a 6.7 Cummins Tuner

A 6.7 Cummins tuner unlocks up to 300HP of delete-safe calibration, returning the power the factory detuned away. Round out the build with our 6.7 Cummins performance parts for the intake and exhaust support that horsepower needs.

End Limp Mode With a 6.7 Cummins Tuner

With DPF, EGR, and DEF removed and tuned, the 6.7L Cummins stops throwing the soft codes that trigger limp mode. A complete 6.7 Cummins delete kit gives you the pipes and hardware to pull those three systems for good.

Improve Throttle Response With a 6.7 Cummins Tuner

A 6.7 Cummins tuner sharpens pedal mapping so the truck pulls cleanly from 1,800 RPM instead of hesitating.
