1998.5-2002 5.9L 24v Cummins Tuning Package

Custom engine and transmission calibration package for the 1998.5–2002 5.9L 24-valve Cummins in RAM 2500/3500 trucks. Covers both ECM and TCM in a single purchase — the most cost-effective way to dial in your entire drivetrain.

What's included

• VIN-matched ECM calibration with multiple switchable power levels
• 47RH / 48RE TCM calibration for firmer, faster shifts and increased line pressure under load
• Datalogging support for ongoing tuning and diagnostics

How it works

Files are delivered via EFI Live (FlashScan V2). After purchase, you submit your VIN and stock tune file; NanoTorque returns custom calibrations you flash yourself. A FlashScan V2 device is required and not included.

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.

All calibrations are developed for emissions-compliant performance and must be used in accordance with applicable local, state, and federal regulations.
