2019–2021 Cummins EFI Live Custom Tuning (File Only)
This is custom EFI Live tuning for 2019–2021 Ram Cummins 6.7L trucks, built for owners who want real control over how their truck drives, not just a generic power increase.
If you already own an EFI Live AutoCal V3, this service delivers a VIN-specific calibration engineered around your truck’s hardware, usage, and driving style.
EFI Live gives access to critical engine control logic, allowing us to refine throttle behavior, torque management, fueling, and timing with precision.
What Changes With EFI Live
Factory 2019–2021 Cummins calibrations are designed around emissions compliance and driveline protection. EFI Live allows controlled adjustments that improve drivability without making the truck feel harsh or unpredictable.
Our tuning focuses on:
-
Smoother, more responsive throttle behavior
-
Strong, usable torque delivery
-
Clean, controlled fueling strategies
-
Improved drivability in daily driving and towing scenarios
-
Power that feels predictable and intentional
The goal is refinement, not chaos.
Supported Trucks
-
2019–2021 Ram 2500 / 3500
-
6.7L Cummins (ISB)
Each model year is tuned with year-specific calibration strategies.
Built Around Your Exact Setup
Every tune is built after reviewing:
-
VIN and ECM configuration
-
Intake, exhaust, turbo, and airflow modifications
-
Fuel system and injector setup
-
Tire size and axle gearing
-
Intended use (daily driving, towing, performance)
Your tune is engineered to work with your combination, not against it.
Power Without Compromising Drivability
More power doesn’t have to mean less control.
Our EFI Live Cummins tuning prioritizes:
-
Linear throttle response
-
Controlled EGT behavior
-
Clean acceleration without unnecessary smoke
-
Smooth, confidence-inspiring drivability
The truck feels sharper, more responsive, and easier to drive.
