2019–2021 Cummins EFI Live AutoCal V3 – Preloaded Custom Tuning
This is the complete, turn-key EFI Live solution for 2019–2021 Ram Cummins 6.7L trucks.
No software to install.
No files to move.
No setup headaches.
Your EFI Live AutoCal V3 arrives fully preloaded with a custom calibration built specifically for your truck, so you can plug it in, flash, and drive — knowing the tune was engineered around your setup from the start.
This is EFI Live done properly: simple on the outside, precise and intentional under the hood.
What’s Included
-
EFI Live AutoCal V3 handheld device
-
Custom EFI Live tune(s) built in-house
-
Tunes preloaded and ready to flash
-
Unlimited free revisions
-
Direct support from your tuner
Everything is configured before it ships. You’re not figuring anything out — you’re just applying the tune.
What Changes After Flashing
From the factory, 2019–2021 Cummins trucks are heavily torque-managed and emissions-driven. EFI Live allows us to refine that logic in a controlled, drivability-focused way.
Expect:
-
Sharper throttle response without harsh engagement
-
Strong, usable torque where you actually drive
-
Smooth, predictable power delivery
-
Improved drivability for daily driving and towing
-
A truck that feels controlled, responsive, and confident
The difference is noticeable immediately — especially at part throttle and under load.
Supported Trucks
-
2019–2021 Ram 2500 / 3500
-
6.7L Cummins (ISB)
Each model year is tuned using year-specific calibration strategies.
Built Around Your Exact Setup
Before tuning, we collect your:
-
VIN and ECM information
-
Full mod list (intake, exhaust, turbo, fuel system, etc.)
-
Tire size and axle gearing
-
Intended use (daily driving, towing, performance)
Your tune is built to work with your combination, not against it.
Unlimited Revisions — We Stand Behind the Tune
Your build and your preferences may change — your tuning support doesn’t.
You get:
-
Unlimited free tune revisions
-
Adjustments based on feedback or datalogs
-
Continued support as your setup evolves
We don’t ship devices and disappear.
