Typical before and after power and torque for every BMW X6 M engine we tune. Your own car is custom mapped on our in-house 4WD dyno, and every map is fully reversible.
Locked ECU? No problem. This V8 has two ECUs, one per cylinder bank, and BMWs built from June 2020 have them encrypted. We unlock both on our own bench the same day — £150 added to a tuning booking — and it adds no time to your appointment. On its own, if we’re not tuning the car, it’s £299.

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.
Spread the cost. From £249.83/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.
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 4 BMW X6 M engines we tune, the X6 M sees the biggest Stage 1 gain: 600bhp to 700bhp and 750Nm to 850Nm, up 100bhp. 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 £1499 inc VAT, and gearbox tuning is £325 or £385 depending on the model. Book both together and you save £125. You can spread it over 6 months at 0% with Bumper, or choose Pay in full when you book and pay 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 ›
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: the car can be put back to its factory software whenever you need.
How long does it take, and is it reversible?
Most Stage 1 tunes take around two hours. If the ECU needs unlocking we do that here on our own bench during the same visit, so it does not make the appointment any longer. 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.
