How Do We Do It?

All standard vehicles have limiters set inside the ECU to accommodate poor servicing, low quality fuels, varying altitudes and general neglect. Manufacturers now all use modular engines whereby the engine power is restricted by the software to serve the various markets, this enables us to achieve power gains which are above and beyond expectations.
We take a complete clone of your engine control units (ECU) software and modify parameters such as turbo boost pressure, ignition timing, fueling, torque limiters and many more in order to provide you with an engine which is safe, reliable and enjoyable but most of all tailored to your car and requirements.
