Every price on this page is a full custom dyno tune

Not a generic file bought in and flashed over the port. Your BMW X1 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, timing, fuelling and temperatures all watched in real time under load: knock on the petrols, rail pressure and exhaust temps on the diesels.
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 £74.84/mo over 6 months at 0% APR, interest free. Or 3 interest-free payments of £149.67 with Klarna. How finance works ›

BMW X1 remapping questions

How much power will a Stage 1 remap add to a BMW X1?

Every BMW X1 engine is different, which is why they are listed separately above. At the top end the 18i picks up 110bhp, going 150bhp to 260bhp with torque up to 420Nm.

How much is Stage 1 tuning on a BMW X1?

A BMW X1 Stage 1 is from £449 inc VAT; gearbox software is £325–£385 on its own, or £125 less when booked with the engine tune. Finance is 0% over 6 months, or 3 payments with Klarna.

Is the ECU locked on a BMW X1?

Only the later cars. From about June 2020 the factory locks the ECU, so it needs unlocking before tuning, which we handle in-house. Pop your registration in and it will tell you either way. Check if your ECU is locked ›

What supporting mods does a BMW X1 need for Stage 2?

It depends on fuel. Diesels need a DPF delete (off-road use only) and an uprated intercooler; petrols need a decat or sports cat downpipe plus an uprated intercooler. Stage 2 cannot be mapped safely on a standard car, so if yours has no supporting hardware we will fit Stage 1 instead.

What happens to my warranty and insurance if I tune my BMW X1?

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 and we keep your original file, so the car can be returned to stock whenever you need.

Can the remap be reversed, and how long does it take?

Most Stage 1 tunes take around two hours, and cars needing ECU unlocking are booked as a 4-hour half-day. It is completely reversible, and your factory file is saved before we touch anything.

Figures are typical results for a healthy, standard vehicle on our dyno. 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.
