About This Tune

EA888 Evo4.
Proper Numbers.

The Audi S3 8Y is powered by the latest EA888 Evo4 2.0 TFSI — one of the most capable and tuneable four-cylinder petrol engines ever built. From the factory it produces 310PS, but with a custom Stage 1 dyno calibration from DC Remapping, the real potential of this engine is unlocked.

We consistently achieve 388bhp and 548Nm on 99RON fuel, transforming the S3 from a quick car into a genuinely rapid one. Throttle response is sharpened significantly, the mid-range pulls harder and the power delivery across the entire rev range is much more linear and progressive.

All calibration is carried out live on our 4WD linked rolling road — every change tested and validated in real time. The result is a tune that feels factory integrated, not aggressive or harsh.

Figures vary depending on fuel quality. Results shown are on 99RON premium fuel. On 97RON you can expect slightly lower figures. We always recommend running 99RON for maximum performance and to get the most from your calibration.

  • 388bhp and 548Nm on 99RON — proven on our dyno
  • Sharpened throttle response and improved mid-range pull
  • No hardware modifications required
  • Full vehicle health check carried out before tuning
  • Before and after dyno printout included
  • Compatible with DL381 S-Tronic gearbox tuning

Customer Reviews

What Our
Customers Say.

★★★★★

"Had my S3 8Y remapped here on 99RON and the difference is incredible. The mid-range torque is on another level and the throttle response is so much sharper. Daniel talked me through everything beforehand and I left with a dyno sheet showing exactly what it made. Brilliant."

Tom H. Audi S3 8Y Owner
★★★★★

"Stage 1 remap and DL381 gearbox tune done on the same day. The combination is absolutely brilliant — the gearbox matches the engine perfectly now. Over 380bhp from a standard S3 is properly impressive. DC Remapping clearly know this platform inside out."

Ryan B. Audi S3 8Y · Stage 1 + Gearbox
★★★★★

"Really happy with the result on my S3. The team were upfront about the difference between 97 and 99 RON which I appreciated — makes a real difference. Car pulls so much harder across the whole rev range now. Would definitely recommend to any S3 owner."
