Helpful Fitment Notes
- Model-year differences: 2019–2024 trucks use updated ECUs; feature availability varies by year/trim. Check each product page for specific compatibility and functions.
- Emissions compliance: Look for products with stated CARB EO numbers or “50-state legal” notes. CPP Diesel does not offer equipment intended to remove or defeat emissions systems.
- Power management: For towing and daily use, conservative calibrations and transmission tuning often deliver the best reliability and temperature control.
- Dealer reflashes: A dealer software update can overwrite calibrations. Keep your device handy to restore approved tunes after service when allowed by the product.
- Best practices: Use a battery maintainer during flashes, record your stock file when applicable, and follow on-screen prompts to avoid interruption.

Tuners & Programmers FAQ – 2019–2024 Ram 2500/3500
Are these devices street-legal?
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.
Will this work on my 2022–2024 truck?
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.
Do I need extra gauges with a tuner?
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.
What happens if the dealer reflashes my ECM?
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.
Can I return to stock settings?
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.
