Unlock usable power, improved drivability, and better monitoring on your 2019–2024 Ram Heavy Duty—with emissions-compliant solutions only. CPP Diesel curates tuners, programmers, digital gauges/monitors, pedal controllers, transmission calibration tools, and OBD-II service gear that fit your 6.7L Cummins while keeping factory emissions equipment intact. Availability can vary by model year and ECU security level—always review product notes and CARB EO details where applicable.
Products indicate legality on each page. Look for CARB EO numbers or “50-state legal” language. Items marked for “competition/off-road” are not for public-road use—always follow local laws.
Some features differ by ECU/security level. Check the compatibility notes by year/trim; when in doubt, contact us with your VIN and we’ll confirm supported functions.
Digital monitors can display EGT (where supported), boost, coolant/trans temps, and more. For heavy towing or performance use, monitoring key temps is strongly recommended.
A dealer update can overwrite calibrations. Many devices allow you to restore an approved tune after service—follow the device instructions and ensure your battery is maintained during any flash.
Yes, most programmers let you save and restore stock calibrations. Always back up your stock file when prompted and keep the device for future updates.
Need help choosing? Send us your VIN, model year, and goals (towing, daily, performance within legal limits) and we’ll recommend the best compliant solution for your Ram.
