Typical before and after power and torque for every Alpina B8 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. 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.
Every price on this page is a full custom dyno tune
Not a generic file bought in and flashed over the port. Your Alpina B8 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.
Alpina B8 remapping questions
How much power will a Stage 1 remap add to an Alpina B8?
Gains vary by engine. The strongest on the Alpina B8 is the 4.4 Bi-Turbo V8, which goes from 621bhp and 800Nm to 680bhp and 850Nm, a gain of 59bhp. Find your engine in the table above for its own numbers.
What does an Alpina B8 remap cost?
Prices start at £999 inc VAT for Stage 1 on an Alpina B8. 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 B8?
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 Alpina B8 be with you, and can it be undone?
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.

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.
