Typical before and after power and torque for every Alpina XD3 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. BMW and Alpina cars built from June 2020 have an encrypted ECU. We unlock it on our own bench the same day — £100 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 £249. Check your reg → · More on unlocking →Built 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.

Not a generic file bought in and flashed over the port. Your Alpina XD3 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, rail pressure, injection timing, fuelling and exhaust 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.

Alpina XD3 remapping questions
What does Stage 1 tuning do for an Alpina XD3?
Gains vary by engine. The strongest on the Alpina XD3 is the 3.0 Quad-Turbo, which goes from 388bhp and 770Nm to 450bhp and 850Nm, a gain of 62bhp. Find your engine in the table above for its own numbers.
What does an Alpina XD3 remap cost?
Prices start at £449 inc VAT for Stage 1 on an Alpina XD3. 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.
Does a remap invalidate the warranty or insurance on an Alpina XD3?
You will need to tell your insurer, as with any modification, and it can affect a remaining manufacturer warranty. Every map is reversible, so the Alpina XD3 can be put back to its factory software at any point.
How long will my Alpina XD3 be with you, and can it be undone?
Allow roughly two hours for Stage 1. A locked ECU is unlocked in-house on the same visit without a longer appointment. Everything is reversible: the Alpina XD3 can go back to its factory software on request.
