6.7L Cummins (CME)

This collection is built for Ram 2500 and 3500 trucks running the 6.7L Cummins CME engine (2013–2018). It includes proven tools like the EFI Live AutoCal V3 Tuner, made to load custom tune files for better towing, smoother shifting or lower EGTs. These tune files are built to fit your truck’s year range with no guesswork.

Prefer on-screen data and quick controls? The Mini Maxx V1 and V2 DPF Delete Tuners work well with CME trucks and pair with the OBD2 to HDMI Adapter Box for live display. All tuners in this collection support off-road delete tuning where local rules allow. Orders include clear setup instructions, free shipping across the U.S. and live phone help if needed.
