Every price on this page is a full custom dyno tune
Not a generic file bought in and flashed over the port. Your BMW M8 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.

BMW M8 remapping questions
How much bhp does a BMW M8 gain from a remap?
Gains vary by engine. The strongest on the BMW M8 is the F92 M8, which goes from 600bhp and 750Nm to 680bhp and 850Nm — a gain of 80bhp. Find your engine in the table above for its own numbers.
What does a BMW M8 remap cost?
Prices start at £749 inc VAT for Stage 1 on a BMW M8. Each engine in the table shows its own price, and adding gearbox tuning at the same time saves £125. 0% finance over 6 months and Klarna are both available.
Will my BMW M8 need unlocking before it can be tuned?
BMW models built from roughly mid-2020 have an encrypted ECU that must be unlocked first. It is done here rather than sent away. Check your registration to see whether your particular car needs it.
Check if your ECU is locked ›Do I need any hardware for Stage 2 on a BMW M8?
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.
Does a remap invalidate the warranty or insurance on a BMW M8?
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 and we keep your original file, so the car can be returned to stock whenever you need.
How long will my BMW M8 be with you, and can it be undone?
Most Stage 1 tunes take around two hours, and cars needing ECU unlocking are booked as a 4-hour half-day. It is completely reversible — your factory file is saved before we touch anything.

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.
