Locked ECU? Already in the price. Every RS Q8 4.0 V8 has a locked Bosch MG1CS008 ECU. We unlock it on our own bench the same day, with no extra time, and the £449 is already included in the prices shown. You can choose to have it sent away instead: £399, 3–4 working days with the car staying with us. On its own, if we’re not tuning the car, it’s £549 in-house or £499 sent away. More on unlockingBuilt from June 2026? Those cars use a new ECU lock that can’t yet be opened, so we can’t tune them for now. Email sales@dcremappinguk.com with your reg and we’ll let you know as soon as that changes.
Every price on this page is a full custom dyno tune
Not a generic file bought in and flashed over the port. Your Audi RSQ8 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.
Spread the cost. From £166.50/mo over 6 months at 0% APR with Bumper, interest free. Or choose Pay in full when you book and pay with Klarna. How finance works › Book engine and gearbox tuning together and save £125.
Audi RSQ8 remapping questions
How much bhp does an Audi RSQ8 gain from a remap?
Gains vary by engine. The strongest on the Audi RSQ8 is the 4.0 BI TURBO 600HP, which goes from 600bhp and 800Nm to 740bhp and 1050Nm, a gain of 140bhp. Find your engine in the table above for its own numbers.
What does an Audi RSQ8 remap cost?
Prices start at £999 inc VAT for Stage 1 on an Audi RSQ8. Each engine in the table shows its own price, and adding gearbox tuning at the same time saves £125. Bumper 0% finance over 6 months and Klarna are both available.
Will my Audi RSQ8 need unlocking before it can be tuned?
It depends on the engine as much as the year. Audis from roughly mid-2020 are locked, and so is the 4.0 V8 TFSI regardless of age. Either way we sort the unlocking: in-house on our bench or sent away, your choice, except the 4.0 V8 ECUs, which have to go away. Give us your reg and we will tell you which applies to yours. Send us your reg and we will confirm ›
Does a remap invalidate the warranty or insurance on an Audi RSQ8?
A remap is an aftermarket modification, so it is your responsibility to declare it to your insurer. It may also affect any remaining manufacturer warranty. Our maps are fully reversible: the car can be put back to its factory software whenever you need.
How long will my Audi RSQ8 be with you, and can it be undone?
Most Stage 1 tunes take around two hours, and if the ECU needs unlocking we do that on our own bench during the same visit, with no extra time. It is completely reversible: the car can go back to its factory software whenever you need.
Ways to paywhen you pay in full0% finance over 6 monthsCard & Apple Pay£50 deposit secures your slotHow finance works ›
Whichever you pick, the total carries through to checkout, so pay in full by card, Apple Pay or Klarna, or secure the slot with a £50 deposit. Figures are typical for a healthy, standard vehicle; your before and after dyno printout shows exactly what your car makes. 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.
