WRX — Stage 3 ECU Tune
- 31% power increase to 179kW
- 26% torque increase to 308Nm
- Crisp throttle response
- Strong mid-range pull
- Improved fuel efficiency
- Optimized boost control at 15psi
This 2011 WRX was prepared for closed-circuit competition use with a well-matched package: GCG 3076 turbo, 1000cc injectors, full exhaust and intake upgrades, and a proper front-mount. The factory ECU was calibrated to 1.03 bar, delivering 179 kW at the wheels and 308 Nm — a 42 kW gain over stock.
The file balances safe AFRs on 98 RON with usable torque through the midrange, where the EJ25 makes its best power. Boost delivery is progressive, ignition timing is conservative given the turbo size, and the larger injector deadtimes are dialled in cleanly.
This setup works well for the platform without chasing peaks. It's a sensible Step 3 build for weekend racing or track days, not a street car.
Is this file suitable for daily driving on pump fuel?
This is a full competition build calibrated for off-road and closed-circuit use. The supporting hardware and boost level are beyond what's appropriate for street use.
What injectors and turbo does this calibration support?
The file is calibrated specifically for 1000cc injectors and the GCG 3076 turbo at 1.03 bar on 98 RON.
Can I run this file with fewer modifications?
No. This is a Stage 3 file requiring the full supporting hardware listed: turbo, injectors, exhaust, intercooler, intake, and fuel system to match.
