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.

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 DQ381 S-Tronic gearbox tuning

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.

★★★★★

Absolutely fantastic service. This isn’t the sort of place that just does a couple of power runs and throws the car off the dyno. You can tell that it truly is custom with the amount of runs I had, tweaking settings giving me an impressive 73bhp on my S3. …

Just had my S3 stage 1 the results are amazing, can tell the difference would recommend DC for anyone else

Gary Adams · Audi S3 · Google review

★★★★★

I'd had a out of the box stage one tune done on my Audi TTS. It was jerky and struggled under load. Took it to DC Remapping and had the tune removed and then a new one put on along with the DSG tune. The car is absolutely night and day in difference when driving it and pushing on. …

FAQs

Audi S3 Tuning Questions

How much power will a Stage 1 remap add to my Audi S3?

Our Stage 1 maps are custom-built on our in-house 4WD dyno and tailored to your exact Audi S3, never a generic off-the-shelf file. You'll see a substantial, fully dyno-proven gain in both power and torque; the headline figures for this platform are shown at the top of this page. Because every map is refined over multiple runs, the results are realistic, repeatable and safe.

Is remapping my Audi S3 safe and reliable?

Yes. We tune strictly within the safe mechanical limits of your Audi S3's engine and gearbox, monitoring temperatures, pressures and torque loads across multiple dyno pulls. We've spent 15+ years tuning these platforms, so our maps prioritise long-term reliability alongside performance.

Will a remap affect my warranty or insurance?

A remap is an aftermarket modification, so it's the owner's responsibility to declare it to their insurer. Our maps are fully reversible, we can return the Audi S3 to its factory software whenever you need, for example before a main-dealer visit.

Is the remap reversible?

Completely. It is fully reversible: your Audi S3 can be put back to its factory software at any time.

Will tuning improve my Audi S3's fuel economy?

We tune for performance, not fuel economy, so we don’t promise or guarantee any MPG saving. How much fuel the car uses comes down mostly to how it’s driven, and using the extra performance will use more.

How long does it take, and do you tune on a dyno?

Most Stage 1 tunes are completed within a few hours; allow up to a day for combined ECU and gearbox work. Every Audi S3 is mapped on our in-house 4WD dyno in Warrington, never on the road, so the result is measured and consistent. You're welcome to relax in our customer waiting area while we work.
