Audi S1 8X — Engine and Performance
The Audi S1 8X is powered by a 2.0-litre TFSI EA888.3 turbocharged petrol engine, producing 231HP and 370Nm of torque as standard. With a suitable ECU calibration, the S1 can benefit from stronger acceleration, improved mid-range response and a more engaging driving experience.
Stage 1 ECU Remap — 300HP / 430Nm
Stage 1 tuning is designed for vehicles with standard hardware that are in good mechanical condition.
- Standard power: 231HP
- Standard torque: 370Nm
- Stage 1 power: 300HP
- Stage 1 torque: 430Nm
A Stage 1 remap optimises the engine calibration to improve power delivery and throttle response without necessarily requiring hardware upgrades, provided the vehicle is suitable for the selected calibration.
Stage 2 ECU Remap — 330HP / 460Nm
For drivers seeking additional performance, Stage 2 tuning offers a supplied target of 330HP and 460Nm.
Stage 2 may require suitable supporting hardware modifications, depending on the vehicle’s existing setup and calibration. Contact Onyx Performance for a quote and confirmation of the modifications required for your Audi S1.
All performance figures are indicative targets rather than guaranteed results. Actual results depend on vehicle condition, fuel quality, installed hardware and calibration.

BEFORE TUNING
Before remapping, we recommend checking the vehicle’s mechanical condition and scanning for fault codes. The engine, turbocharger, ignition system, cooling system and transmission should be in good working order before performance tuning begins.

Regular servicing is important for a tuned vehicle. Keep engine oil, filters, spark plugs and other service items maintained according to the manufacturer’s recommendations. Address any existing mechanical or diagnostic issues before increasing engine output.
EXHAUST UPGRADES
An appropriate exhaust upgrade can complement a performance setup. Any exhaust modifications should be compatible with the engine calibration and comply with applicable emissions and road-use requirements.
PERFORMANCE UPGRADES
Depending on your performance goals, supporting upgrades may include improved intercooling, intake components, exhaust modifications and other suitable hardware. We can discuss your existing setup and advise on the requirements for your intended tuning stage.
