Typical before and after power and torque for every BMW Z8 engine we tune. Your own car is custom mapped on our in-house 4WD dyno, and every map is fully reversible.
Every price on this page is a full custom dyno tune
Not a generic file bought in and flashed over the port. Your BMW Z8 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 Z8 remapping questions
What gains can I expect from Stage 1 on a BMW Z8?
Gains vary by engine. The strongest on the BMW Z8 is the 5.0 V8, which goes from 400bhp and 500Nm to 415bhp and 525Nm, a gain of 15bhp. Find your engine in the table above for its own numbers.
What does a BMW Z8 remap cost?
Prices start at £449 inc VAT for Stage 1 on a BMW Z8. 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.
Will my BMW Z8 need unlocking before it can be tuned?
BMW models built from roughly mid-2020 have an encrypted ECU that must be unlocked first. It is done here rather than sent away. Check your registration to see whether your particular car needs it. Check if your ECU is locked ›
Does a remap invalidate the warranty or insurance on a BMW Z8?
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 BMW Z8 can be put back to its factory software at any point.
How long will my BMW Z8 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 BMW Z8 can go back to its factory software on request.
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.
