What Could You Gain?

Real figures, not guesswork

Every engine is different, so instead of a one-size-fits-all number, we’ll tell you exactly what your vehicle can achieve. As a guide, Stage 1 remaps typically add around 25–35% more power and torque, with stronger mid-range pull and, on an economy map, the potential for better MPG.

Send us your make, model and engine and we’ll come back with a realistic expectation and a free quote.

The Process

How It Works

Straightforward from first contact to driving away.

  1. 1

    Get in touch

    Send us your make, model, year and engine. We’ll confirm what’s possible and give you a free, no-obligation quote.

  2. 2

    Book in

    We arrange a time that suits you. Most remaps are completed the same day.

  3. 3

    Read & back up

    Your original ECU file is read and backed up safely before any changes are made.

  4. 4

    Custom map & flash

    We build a map tailored to your vehicle, write it to the ECU and test that everything runs as it should.

  5. 5

    Drive away

    You leave with a sharper, stronger vehicle, and we’re only a call away afterwards.

Peace of mind: your original ECU file is always backed up first, so your vehicle can be returned to standard if you ever need to. Remember a remap is a modification, so please declare it to your insurer.

Is remapping safe for my engine?

A properly developed remap works within safe limits for your engine. We build a custom map for your vehicle rather than using a generic file, and we always back up your original file so it can be returned to standard if needed.

Will a remap void my manufacturer warranty?

A remap can affect your manufacturer warranty, particularly on drivetrain components. If your vehicle is under warranty, weigh this up before going ahead. We’re happy to talk it through honestly so you can make an informed decision.

Do I need to tell my insurer?

Yes. A remap is a modification and you should declare it to your insurer. Not declaring modifications can invalidate your policy. We always recommend being upfront with your insurance company.

Can the remap be reversed?

Yes. We back up your original ECU file before making any changes, so your vehicle can be returned to its standard map if you ever need to.

Will it improve my fuel economy?

It can, particularly with an economy-focused map and a sensible driving style. Results vary by vehicle and how it’s driven, so we’ll give you an honest expectation for yours.

How much power will my car or van gain?

It depends on the vehicle and engine. Stage 1 remaps typically add around 25–35% more power and torque. Get in touch with your make, model and engine and we’ll tell you what yours can realistically achieve, for free.

How long does it take?

Most remaps are completed the same day. Get in touch and we’ll give you a time estimate when we book you in.

What about AdBlue, DPF and EGR work?

We offer AdBlue, DPF and EGR solutions on a custom, vehicle-specific basis. Get in touch with your make, model and engine and we can advise on what is possible for yours. Please see our Terms for the conditions these services are offered under.
