Book

Every price on this page is a full custom dyno tune

Not a generic file bought in and flashed over the port. Your Alpina B3 S 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 £74.83/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.

Alpina B3 S remapping questions

How much power will a Stage 1 remap add to an Alpina B3 S?
Every Alpina B3 S engine is different, which is why they are listed separately above. At the top end the 3.5i picks up 50bhp, going 400bhp to 450bhp with torque up to 600Nm.
How much is Stage 1 tuning on an Alpina B3 S?
An Alpina B3 S Stage 1 is from £449 inc VAT; gearbox software is £325 on its own, or £125 less when booked with the engine tune. Finance is 0% over 6 months with Bumper, or choose Pay in full when you book and pay with Klarna.
What happens to my warranty and insurance if I tune my Alpina B3 S?
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.
Can the remap be reversed, and how long does it take?
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.

Other Alpina models

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.
