Colorado RG — Stage 2 ECU Tune
- 34% power increase
- 22% torque increase
- Improved fuel efficiency
- Enhanced boost control
- Optimized fuel delivery
- Better throttle response
The RG Colorado's 2.8-litre diesel responds well to the basics done properly. This Stage 2 file pairs improved air intake with boost control optimisation, high-pressure fuel pump tuning, and injector calibration to lift output from 70 kW to 94 kW at the wheels, with torque stepping up from 235 Nm to 287 Nm.
The workshop ran the dyno calibration to dial in throttle response and manage fuelling under load—critical for touring setups where weight and heat are constants. The tune keeps the factory ECU architecture intact, focusing on margin and driveability rather than chasing peak numbers. Torque delivery suits long highway hauls and steady towing without excess smoke or harsh cut-in.
What modifications are required for this Stage 2 file?
The file requires an improved air intake, along with boost control optimisation, high-pressure fuel pump tuning, and injector optimisation. It's dyno-calibrated to ensure fuelling and delivery are matched to the hardware.
Is this tune suitable for daily driving and towing?
Yes. The torque curve and fuelling strategy are calibrated for real-world use, including towing and loaded touring. The gains provide better overtaking ability and reduced gearbox hunting without compromising reliability.
Does the tune affect fuel economy?
Economy depends on driving style, but the optimised fuel delivery and reduced throttle demand under light load typically improve efficiency during highway cruising.
