2019-2026 6.7L Cummins Tuning Package

Complete engine and transmission calibration package for the 2019–2026 6.7L Cummins in RAM 2500/3500 trucks. Fifth-generation trucks added the Security Gateway Module (SGW) — read the fitment note below before ordering. This is the full-drivetrain solution covering both ECM and TCM.

What's included

• VIN-matched ECM calibration with multiple switchable power levels
• 68RFE or Aisin AS69RC TCM calibration matched to your transmission
• Datalogging support for ongoing tuning and diagnostics

How it works

Delivered via EFI Live (FlashScan V2). Submit your VIN and stock files; NanoTorque returns custom calibrations you flash yourself. A FlashScan V2 device is required and not included. 2018+ trucks require an SGW (Security Gateway) bypass cable to allow the FlashScan to communicate with the ECM — this cable is not included and must be sourced separately before flashing.

Support tiers

• Limited (4 Weeks): Revision window open for four weeks; tune stays loaded on your tool afterward.
• Full (Lifetime): Unlimited revisions and lifetime access as your build evolves.

Intended for off-road and motorsport use only. Not for use on public roads where emissions regulations apply.
