What are RaceME Custom Tunes?
Why Settle for Standard? The RaceME Custom Advantage.
Explain the difference: While your RaceME Ultra tuner comes with powerful pre-loaded tunes, RaceME Custom Tunes™ are precisely calibrated files designed exclusively for your truck. We analyze your specific RAM (year, model, engine specs, and any modifications you’ve made) to create a tune that extracts every ounce of safe performance.
- Personalized Calibration: Not one-size-fits-all.
- Optimized for Your Mods: Perfect for modified turbos, injectors, exhaust systems.
- Tailored to Your Use: Daily driver, heavy hauler, extreme off-road, or competition.
- Unrivaled Precision: Every parameter (fueling, timing, boost, shift points) finely adjusted by our experts.

Experience the RaceME Difference: Features You Control.
Your Truck. Your Tune. Your Way.
Highlight the unique features and levels of control our custom tunes offer.
Shift-on-the-fly Performance
Our Custom Tunes support 5-position switch tuning, allowing you to instantly change power levels and driving characteristics with a flick of a switch – no re-flashing needed. Go from Tow to Race in seconds!
Ultimate Drivability & Longevity
We fine-tune the shift patterns for your Chrysler/Japanese transmission to deliver seamless, powerful shifts under all conditions. This reduces slip, lowers transmission temperatures, and significantly extends the life of your drivetrain.
Signature Cummins Sounds
Want to make your RAM sound as powerful as it performs? Our Custom Tunes can include unique engine characteristics like Lope Sound (in 3 stages), Whistle Sound, and classic 12-Valve Sound – adding a distinctive roar to your truck.
Precision Hp Stage
Choose from precisely calibrated power levels, from +30HP for enhanced daily driving, all the way up to +200HP for maximum raw performance. Our experts dial it in for your exact needs.
Maximized Fuel Economy
Even with increased power, our custom tunes prioritize efficiency. By optimizing combustion and shift timing, you can see significant fuel consumption reductions – saving you money on every mile.
