Stage 1 / Stage 2 Remap
A remap changes the software in your engine's ECU to improve performance.
A remap changes the software in your engine's ECU to improve performance.
Stage 1 Remap:
Designed for stock vehicles. Safely increases horsepower and torque with no physical modifications. Improves throttle response and fuel economy.
Stage 2 Remap:
Requires supporting hardware like a sports exhaust, intercooler, or intake. Offers more aggressive power gains. Perfect for enthusiasts who want performance upgrades beyond factory limits.
Unlike many tuning providers, we don't just upload pre-made solutions. Every remap we carry out is individually programmed and tailored to your specific vehicle, ensuring optimal performance, reliability, and safety. Whether you're looking for more power, improved fuel economy, or a smoother drive - we deliver results at your door.

Frequently Asked Questions
Yes, ECU remapping is legal in the UK. However, the vehicle must remain roadworthy and compliant with MOT emissions requirements. Any modifications should also be declared to your insurance provider.
Yes. A professional remap always includes saving the original factory ECU software. The vehicle can be returned to stock at any time if required, for example before selling the car or returning a lease vehicle.
Not necessarily. Under normal driving conditions, many vehicles see equal or slightly improved fuel economy due to improved torque and efficiency. Fuel consumption will increase only if the additional power is used frequently.
It can be, provided the vehicle is mechanically sound. This is why pre-remap diagnostics are essential. A well-maintained high-mileage engine can safely benefit from a conservative Stage 1 ECU remap.
A properly tuned Stage 1 ECU remap should not cause MOT issues, as long as emissions systems remain intact and the vehicle passes emissions testing. Poor-quality remaps or removal of emissions equipment can lead to MOT failure.
Most Stage 1 ECU remaps take between 1-3 hours, depending on the vehicle and ECU type. Some models may take longer if bench or boot-mode access is required.
A custom ECU remap is generally superior to a tuning box. Remapping directly adjusts multiple engine parameters in a controlled way, whereas tuning boxes typically manipulate limited sensor signals and offer less precise control.
