TOYOTA GR YARIS STAGE 1 REMAP
Standard: 261HP / 360Nm
Stage 1: Up to 315HP / 430Nm
Stage 1 tuning is ideal for standard or lightly modified Toyota GR Yaris models. It is designed to increase power and torque while retaining smooth, reliable performance for everyday driving. Major engine hardware upgrades are normally not required for a Stage 1 remap.
A Stage 1 remap can improve:
- Power and torque

- Acceleration
- Mid-range performance
- Overtaking performance
- Overall engine response
The result is a stronger, more responsive GR Yaris while maintaining the flexibility needed for everyday road use.
As the GR Yaris is a petrol vehicle, we recommend checking spark plugs and ignition components before tuning. Any existing misfires or ignition issues should be diagnosed before a remap is carried out.
TOYOTA GR YARIS STAGE 2 REMAP
Standard: 261HP / 360Nm
Stage 2: Up to 345HP / 460Nm
