Mustang GT — Stage 2 ECU Tune
- 6% power increase to 266kW
- 4% torque increase to 694Nm
- Improved power delivery across RPM range
- Enhanced torque characteristics
- Optimized boost control strategy
- Refined fuel injection mapping
The 2017 Mustang GT runs a factory ECU that responds well to recalibration once you sort the fuel system and throttle mapping. This Stage 2 file was built around upgraded high-pressure fuel pump and larger injectors, with drive-by-wire calibration dialled in to smooth out the throttle response that can feel a bit binary from the factory.
The dyno recorded 266 kW at the wheels, up from 251 kW, with torque climbing from 667 Nm to 694 Nm on 98 RON. The boost control and solenoid changes let us run a more consistent curve without the factory taper, and the injector scaling keeps mixtures tight under load. Nothing wild, but a solid result for a streetable setup that keeps the Coyote happy in Australian heat.
What does the drive-by-wire calibration change in practice?
It smooths out the throttle map so the car feels more linear and predictable off the line and through part-throttle. The factory calibration can be quite aggressive in the first third of pedal travel.
Is this tune safe for daily driving on 98 RON?
Yes. The file was built for 98 RON pump fuel with good headroom. The upgraded fuel pump and injectors support the power increase without running the system hard.
Why are boost control mods listed if it's naturally aspirated?
That's a data entry quirk. The Coyote is naturally aspirated—no boost involved. The tune focuses on fuel, ignition, and throttle calibration.
