Every price on this page is a full custom dyno tune
Not a generic file bought in and flashed over the port. Your BMW X6 M 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 X6 M remapping questions
How much bhp does a BMW X6 M gain from a remap?
It depends which engine you have. Across the 2 BMW X6 M engines we tune, the 4.4 V8 Bi-Turbo sees the biggest Stage 1 gain: 575bhp to 680bhp and 750Nm to 850Nm, up 105bhp. Every figure on this page is for that exact engine.
How much does it cost to remap a BMW X6 M?
Stage 1 custom dyno tuning on a BMW X6 M starts at £599 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 BMW X6 M need its ECU unlocking?
If it was built from around June 2020 onwards, yes. Those ECUs are locked from the factory and have to be unlocked before anything can be written. We do it in-house. Check your registration and we will tell you straight away whether yours is affected.
Check if your ECU is locked ›What does Stage 2 need on a BMW X6 M?
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 BMW X6 M affect my warranty or insurance?
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 does it take, and is it reversible?
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, and your factory file is saved before we touch anything.

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.
