Stage 1 Remap
Stoke-on-Trent, Staffordshire & Cheshire East
A Stage 1 remap rewrites your ECU software to safely unlock the power your engine already has — no hardware changes needed. Expect more BHP and torque, sharper throttle response and often better fuel economy on a steady cruise. Every map is custom-written for your exact engine and ECU, with the original file backed up first.

The basics
What is a Stage 1 remap?
A Stage 1 remap is a custom ECU software upgrade for a standard, unmodified vehicle. We optimise fuelling, boost and timing within safe factory tolerances to release extra BHP and torque, sharpen throttle response and, on many turbo-diesels, improve economy at a cruise. It is the single most cost-effective upgrade for everyday drivability. Want a rough idea of your car’s gains? Try our remap calculator or send us your reg.
What you gain
More power & drivability
Typical Stage 1 gains are a strong lift in BHP and torque, with the biggest real-world benefit being mid-range pull and throttle sharpness that makes overtaking and towing easier.
Turbo-diesels and modern turbo-petrols respond especially well.
How we do it
A custom file, written safely
We read and back up your ECU, build a map matched to your exact engine, then write and road-test it. Safe limits are respected so reliability and engine longevity are protected.

The process
How a Stage 1 remap works
A clear process from the moment you drop the vehicle at our Fenton workshop.
1
Health check first
We scan for existing faults and confirm the engine is healthy before any tuning begins.
2
Read & back up the ECU
Using professional tools we read your ECU file safely and store a full backup of the original.
3
Write the custom Stage 1 map
A map built for your engine and ECU is written within safe limits — not an off-the-shelf file.
4
Road test & confirm
We road-test the result and confirm the gains and clean running before you collect.

Tell your insurer. A remap is a modification and should be declared to your insurer. We keep all changes within safe limits and back up your original file, so the vehicle can be returned to standard if you ever need to.
What a Stage 1 remap gives you
Real-world benefits drivers notice from day one.
More power & torque
A meaningful increase in BHP and especially torque, where you feel it most — mid-range pull for overtaking, towing and loaded driving.
Sharper, smoother delivery
Crisper throttle response and a smoother power curve make the car feel more responsive and easier to drive every day.
Potential fuel savings
Many turbo-diesels return better economy at a steady cruise after a Stage 1 remap, because less throttle is needed for the same pace.

FAQ
Stage 1 remap — common questions
Quick answers before you book. Can't see yours? Call 07404 022260.
What is a Stage 1 remap?
A Stage 1 remap is a custom ECU software upgrade for a standard, unmodified vehicle. It safely optimises fuelling, boost and timing to release more BHP and torque, sharpen throttle response and often improve economy — with no hardware changes needed.
How much does a Stage 1 remap cost?
Stage 1 remaps start from £150. The exact cost depends on your vehicle and ECU type, so we give you a clear quote up front with no surprises. For a quick estimate of your gains and to get a price, use our remap calculator or call us with your make, model and year.
Are there any disadvantages to remapping a car?
Done properly, a quality Stage 1 remap is reliable. The honest points to know: it should be declared to your insurer, you should keep up with servicing and use good fuel, and a poor-quality map can cause problems — which is why we write custom maps within safe limits and back up your original file.
Will a remap affect my warranty or insurance?
A remap is a modification, so you should declare it to your insurer, and it may affect a manufacturer warranty on newer vehicles. We keep your original file so the car can be returned to standard if needed. If in doubt, talk to us first.
Is a Stage 1 remap safe and reversible?
Yes. We stay within safe factory tolerances to protect reliability, and because we back up your original ECU file the remap can be fully reversed at any time.
