EDGE PRODUCTS 85400-300 EVOLUTION CTS3 FOR 2003–2012 DODGE RAM CUMMINS
The EDGE PRODUCTS 85400-300 EVOLUTION CTS3 is Edge’s all-in-one tuner and full-color touchscreen monitor for 2003–2012 Dodge Ram Cummins trucks. It delivers multiple performance tunes (tow, street, performance) through the OBD-II port, while the 5" capacitive touchscreen keeps an eye on critical data like EGT, boost, transmission temperature, rail pressure, regen status and more – all in one clean, factory-style installation.
This CTS3 Evolution is 50-state legal (CARB EO D-802-13) when used per the manufacturer’s application guide and is designed for 2003–2012 Ram 2500/3500 5.9L & 6.7L Cummins. Power levels can offer gains of up to +120 HP and +315 lb-ft of torque on select calibrations, giving your truck stronger towing performance, faster throttle response and smoother overall drivability while still keeping emissions compliance in check.
- 5" full-color capacitive touchscreen with swipe navigation and auto-dimming
- OBD-II plug-and-play install – no wiring or under-hood controller required
- Multiple power levels for towing, daily driving, and performance
- Built-in performance timers (0–60, 1/4-mile, and more)
- Advanced integrated data logger with export capability
- Read and clear DTCs directly from the CTS3 screen
- Wi-Fi updateable so your tuner stays current with Edge’s latest calibrations
- Fully compatible with Edge’s Expandable Accessory System (EAS) for EGT, boost, fuel pressure, and more add-on sensors
FITMENT – EDGE PRODUCTS 85400-300 EVOLUTION CTS3
This Evolution CTS3 tuner is engineered specifically for the following Cummins-powered Ram applications:
- 2003–2007 Dodge Ram 2500/3500 5.9L Cummins (all cab and bed configurations, most trim levels)
- 2007.5–2012 Ram 2500/3500 6.7L Cummins (including manual and automatic transmission trucks)
Always verify your exact year, engine, and existing modifications against Edge’s application guide before installing tunes, especially if you’ve changed injectors, turbochargers, or emissions equipment.
HOW THE EVOLUTION CTS3 HELPS YOUR CUMMINS
- TOWING: Tow-calibrated tunes help improve low-end torque and midrange pull while keeping EGTs in check, ideal for trailers, campers, and equipment.
- DAILY DRIVING: Cleaner throttle response and firmer power delivery make the truck feel lighter and more responsive without sacrificing reliability.
- PERFORMANCE: Higher performance levels provide aggressive gains for unloaded driving, track days, and dyno events when you want maximum power.
- MONITORING: Replace multiple analog gauges with one CTS3 screen that can display dozens of parameters and user-configurable layouts.
- DIAGNOSTICS: Read and clear codes without a scan tool, and use integrated data logging to troubleshoot issues or dial in your setup.

FREQUENTLY ASKED QUESTIONS – EDGE 85400-300 EVOLUTION CTS3
How much power can the EDGE 85400-300 add to my 2003–2012 Cummins?
Exact gains depend on your model year, engine, and selected power level, but many applications see up to around +120 HP and +315 lb-ft over stock on the higher tunes. Tow and daily driving levels offer more conservative gains focused on reliability, EGT control, and drivability. Always monitor EGT and trans temps when using higher power levels.
Is the Evolution CTS3 85400-300 really 50-state legal?
Yes – this part number carries a CARB Executive Order (EO) D-802-13 and is listed as Emission Code 1 by Edge, meaning it is approved for use on emissions-controlled vehicles in all 50 states when installed and used according to the application guide. It is your responsibility to confirm that your specific truck and configuration are covered before installation.
Do I need an EAS EGT probe with this tuner?
The CTS3 screen will show factory parameters without extra sensors, but for tuned Cummins trucks – especially when towing or running higher power – we strongly recommend adding an Edge EAS EGT kit such as the EDGE PRODUCTS 98620 EAS EGT STARTER KIT or the EDGE PRODUCTS 98623 EAS STREET DIESEL KIT so you can watch exhaust temps and keep your engine safe.
Can I still use my CTS3 as a gauge display if I’m not tuned?
Absolutely. The Evolution CTS3 functions as both a tuner and a powerful monitoring device. You can run a stock-level calibration and still use the screen to display multiple custom gauge layouts, log data, and read/clear trouble codes – or pair it with an Insight CTS3 on another vehicle for monitoring only.
Does this tuner support transmission tuning on my Ram?
The 85400-300 Evolution CTS3 focuses on engine tuning and on-screen monitoring. It does not replace a full built transmission or dedicated transmission controller, but the power levels are designed with stock drivetrains in mind. If you tow heavy or run higher tunes often, we recommend supporting upgrades (transmission tuning, converter, input shaft, etc.) to maintain long-term durability.
How do I update the software and calibrations?
The CTS3 features built-in Wi-Fi update capability. Connect the device to a stable Wi-Fi network, follow the on-screen prompts to check for updates, and the unit will download and install the latest firmware and calibration files from Edge. Keeping the tuner updated ensures you have the newest features, bug fixes, and application support.
