Benefits of Remapping:

More BHP & Torque

You can expect anywhere up to 40% more power from getting your vehicle remapped by an expert.

Better Fuel Economy

Most of our Stage 1 remaps will benefit the fuel economy but if fuel economy is your main goal we can focus the remap on fuel efficiency.

Enhanced Throttle Response

Remapping the ECU can improve throttle response, making the engine more responsive to the driver's input. This can lead to a smoother and more enjoyable driving experience.

Preservation of Manufacturer Safety Limits

We ensure that the modifications stay within safe limits set by the manufacturer, protecting the engine and other components from potential damage.
