Every price on this page is a full custom dyno tune
Not a generic file bought in and flashed over the port. Your Audi S4 is strapped to our in-house 4WD dyno and the map is written for your car, on the day, from its own data.
- Health check firstWe look the car over and read the fault memory before we touch anything. If something is wrong, you get told. We don't map over a problem.
- Live data loggingBoost, ignition timing, fuelling, knock and temperatures all watched in real time while the car is running under load.
- Custom calibration on the dynoThe map is built and adjusted run by run against what your engine is actually doing, not what a file supplier assumed.
- Before and after printoutYou leave with the graph: your standard figures and your tuned figures, measured on the same rollers, the same day.

Audi S4 remapping questions
What does Stage 1 tuning do for an Audi S4?
It depends which engine you have. Across the 3 Audi S4 engines we tune, the S4 3.0 TFSI sees the biggest Stage 1 gain: 333bhp to 400bhp and 440Nm to 520Nm, up 67bhp. Every figure on this page is for that exact engine.
How much does it cost to remap an Audi S4?
Stage 1 custom dyno tuning on an Audi S4 starts at £449 inc VAT, and gearbox tuning is £325. Book both together and you save £125. You can spread it over 6 months at 0%, or pay in 3 interest-free instalments with Klarna.
Does my Audi S4 need its ECU unlocking?
Quite possibly. Most Audis built from around June 2020 have a factory-locked ECU, and the 4.0 V8 TFSI cars (SQ7, SQ8, RS6, RS7, RSQ8, S8 and the V8 A8, Q7 and Q8) are locked well before that date too. We unlock all of them in-house. Send us your registration and we will confirm exactly where yours stands before you book.
Send us your reg and we will confirm ›What does Stage 2 need on an Audi S4?
A decat or sports cat downpipe and an uprated intercooler. Stage 2 is not something we can map safely on a standard car, so without the hardware we would fit Stage 1 and you can step up once it is fitted.
Will remapping my Audi S4 affect my warranty or insurance?
You will need to tell your insurer, as with any modification, and it can affect a remaining manufacturer warranty. Because we save your original software first, the Audi S4 can be put back to standard at any point.
How long does it take, and is it reversible?
Allow roughly two hours for Stage 1, or a half-day if the ECU needs unlocking first. Everything is reversible: we store your original software so the Audi S4 can go back to stock on request.
Ways to pay

Whichever you pick, the total carries through to checkout, so pay in full by card, Apple Pay or Klarna (3 interest-free payments), or secure the slot with a £50 deposit. Figures are typical results for a healthy, standard vehicle on our dyno. Your car’s actual output depends on its condition, fuel quality and any supporting modifications. Prices shown are for Stage 1 custom dyno tuning inc VAT; locked ECUs (most BMW and Audi registered from mid-2020) carry an additional unlocking charge, confirmed when you book.
