Audi S3 Remap And Tuning Guide: Stage 1 And 2 Gains By Generation

The Audi S3 shares its EA888 2.0 turbo and Quattro drivetrain with the Golf R, which makes it a compact, all-weather car with a lot of tuning potential. Here’s what a remap does for each generation, what it costs, and what we’ve measured on our own dyno.

These are typical figures from our tuning catalogue. Every car is mapped and measured on our dyno, and your before-and-after printout shows exactly what yours makes. Enter your reg to see the figures and price for your exact S3.

What we measured on our dyno

An 8Y S3 went from 315hp and 418Nm to 388bhp and 548Nm after a custom Stage 1, on 99 RON fuel. That’s more than the typical catalogue figure because the map was developed live for that car rather than taken from a generic file. The full results are on our Audi S3 8Y page.

Stage 1 vs Stage 2 on an S3

Stage 1 is software only: no parts, same-day, and fully reversible. Stage 2 adds supporting hardware such as a downpipe, intake and intercooler, so the map can safely ask for more. On the later cars fitted with a petrol particulate filter (GPF) we focus on Stage 1; ask us about Stage 2 for your exact car.

Tune the S-Tronic too

Early 8V S3s use the 6-speed DQ250 S-Tronic and later cars the 7-speed DQ381. Both respond very well to DSG / S-Tronic gearbox tuning: faster, firmer shifts, launch control and a higher torque limit so the gearbox doesn’t hold back the engine tune.

Quattro needs a 4WD dyno

Being four-wheel drive, the S3 has to be mapped on a 4WD dyno that loads all four wheels safely, which is exactly what we run in-house. Use 99 RON super unleaded for the best results from a petrol tune.

Audi S3 remap FAQs

How much power does a Stage 1 Audi S3 make?

Typically around 360–380hp and 500Nm, depending on the generation. Our own 8Y S3 made 388bhp and 548Nm on 99 RON.

How much is an Audi S3 remap?

A custom Stage 1 is £449, and Stage 2 on the 8V is £599. S-Tronic gearbox tuning is £325, and booking engine and gearbox together saves £125.

Do I need a downpipe for Stage 1?

No. Stage 1 is software only. Stage 2 is the step that needs supporting hardware such as a downpipe, intake and intercooler.

Should I tune the S-Tronic gearbox as well?

We recommend it. A Stage 1 adds a lot of torque, and the factory gearbox software limits anything it sees as too high. Tuning it raises that limit and sharpens the shifts.

Is an S3 remap reversible?

Yes. We keep your original file, so the car can be returned to standard at any time. Remember to declare the remap to your insurer.
