What we actually do
A quick rundown before you book, so you know exactly what you're getting.
Performance Tuning
Performance remapping adjusts your vehicle's fuel, ignition, and boost maps to unlock power and torque your engine has but the factory setup doesn't use. It's done through the ECU rather than physical parts, so it's a same-day job with results you can feel straight away — sharper throttle response, stronger pull through the rev range, and a more engaging drive.
Economy Tuning
Economy remapping takes the opposite approach — instead of chasing power, we smooth out the power delivery and refine the fuelling to reduce how hard the engine has to work for everyday driving. It's popular with high-mileage drivers and van owners who want better miles-per-gallon without changing how the vehicle feels to drive day to day.
AdBlue, EGR & DPF Solutions
AdBlue (SCR), EGR, and DPF systems are all designed to cut emissions, but they're also common causes of warning lights, limp mode, and expensive dealer bills — especially on older or high-mileage cars and vans, where clogged filters, failed sensors, or a faulty AdBlue system can leave a vehicle undriveable. We diagnose the fault and, where appropriate, apply a software solution to get you back on the road.
Sensor Deletes & Fault Fixes
A single faulty sensor can trigger fault codes, warning lights, or limp mode even when the rest of the vehicle is fine. Where a sensor has failed or a part is no longer fitted, we can recalibrate the ECU so it stops flagging a fault that no longer applies — a straightforward fix for a problem that would otherwise mean a trip to the dealer.
AdBlue, EGR, DPF, and sensor delete solutions are carried out based on your vehicle's condition and intended use. We'll always talk through what's right for your car or van before any work is booked in.
Post-2020 Protected ECU Unlocking
Same day — just bring the car to us.
We can now unlock Locked/Protected ECUs from vehicles produced post-2020 — bring your car to us and we'll have it unlocked the same day, ready to remap.

Stock
If your car's already been remapped or has any of the above solutions applied and you want it back to how it left the factory — for a sale, a warranty job, an MOT, or just peace of mind — we can restore the original manufacturer map. Same process as a remap, just putting everything back rather than changing it.
Economy Map
An economy map isn't about power — it's about efficiency. We smooth out the fuelling and refine how the engine delivers power so it doesn't have to work as hard for everyday driving, which means better miles-per-gallon without changing how the car feels to drive day to day.
Popular with high-mileage drivers, vans, and anyone doing a lot of motorway miles.
Stage 1
A Stage 1 remap is a software-only tune on an otherwise standard car — no physical modifications required. We adjust the fuel, ignition, and boost maps within what the factory hardware (turbo, injectors, intercooler) can safely handle, unlocking the power and torque that's already there but held back by the factory setup.
It's the entry point for most cars, and usually where we start.
Stage 2
Stage 2 pushes further than the factory hardware is comfortable supporting on software alone, so it comes paired with supporting modifications — typically an upgraded exhaust or downpipe, a better intake, and often an intercooler upgrade to keep temperatures in check. On some cars, a stronger clutch is needed too, since the extra torque can overwhelm a stock one.
We'll tell you exactly what your specific car needs before any work is booked in.
Stage 3
Stage 3 is where we're building toward serious power, and it generally means going beyond the factory turbo altogether — a hybrid or aftermarket turbo, larger injectors, an uprated fuel pump, and stronger supporting hardware throughout. Depending on the target, that can also mean a built engine with forged internals and a standalone ECU rather than remapping the factory one.
This is fully bespoke work — every Stage 3 build is quoted and planned around your car and your goals.
Locked ECU?
Do you have a locked ECU on a post-2020 car/van? No problem here, we can unlock them and have it back with you within 5-7 working days. Please contact us for more info.

Questions we get asked a lot
Anything not covered here, just message us and we'll talk it through.
Is remapping safe? Will it damage my engine?
We map within your engine's safe operating limits, the aim is to unlock performance the hardware can handle. If a car isn't in a fit state to be mapped, we'll tell you rather than take the booking.
Will it void my manufacturer warranty?
If your vehicle is still under manufacturer warranty, a remap is a modification and could affect a claim, particularly anything engine or drivetrain related. Policies vary between manufacturers, so it's worth checking yours. We can return your ECU to stock at any point if you need it back to standard for a service, warranty work, or selling the car.
How much power will I actually gain?
It depends heavily on your engine. As a rough guide, turbocharged diesels tend to see the biggest gains from a Stage 1, turbocharged petrols a little less, and naturally aspirated engines the smallest — they simply have less headroom to unlock without hardware changes. Rather than quote a generic percentage, send us your reg through the Power Gains form and we'll come back with realistic figures for your exact vehicle.
Power Gains Form →Will it improve or worsen my fuel economy?
That's down to your right foot. More power available means it's easy to use more fuel. But driven normally, the extra torque often means fewer gear changes and less effort which is where economy improves. If economy is your main goal rather than power, enquire about economy map instead.
How long does it take?
Most Stage 1 remaps are typically done in under 2 hours, including reading the ECU, writing the map, and testing. Stage 2 and more involved work takes longer, and locked ECUs that need sending away are normally 5-7 working days. We'll give you a realistic time when you book, so you're not left guessing.
Book Now →Can it be put back to standard?
Yes. We save your original file, so we can restore the factory map whenever you need! For a warranty job, an MOT, selling the car, or if you simply can't handle the speed anymore.
Do you come to me?
Yes — we're based in Hyde, Greater Manchester and cover all of mainland England and Wales.
