The 3 L engine in the RAM 3500 is at the top end of what this displacement produces — serious injection pressure, sophisticated turbocharger management, and a factory calibration that leaves room on the table by design. These engines are well-engineered enough that a careful, dyno-developed map extracts meaningful gains without asking anything the hardware isn't already built to handle.
Our dyno-developed map for the RAM 3500 adds an average of 52 kW (24%) at the wheels and 173 Nm (16%) of engine torque. At this level the car genuinely changes character — overtaking on single-lane highways stops being a commitment, and the mid-range pull from around 1,500 to 3,000 rpm is transformed. You notice it most on the highway on-ramp and in the first third of an overtake.
In practical terms, that works out to around 14 fewer tanks of diesel over 40,000 km. At a typical 15,000 km annual mileage, most RAM 3500 owners save roughly 378 L and $680 per year at the pump — purely from improved combustion efficiency at part-throttle, where diesels spend most of their time.
This RAM 3500 variant was sold in 2018 only. We hold the original factory calibration file for that model year and develop the map on our dyno against that specific ECU — not a generic file that also fits a different year or spec.
