*Performance gains are commensurate with age, mileage, and condition of the vehicle, along with environmental conditions and grade of fuel.
Remapping is a process where the parameters within the tuning and calibration of the ECU are changed to increase the performance and/or the economy of the engine are modified to improve the characteristics of the engine.
There are many maps within an engine ECU, controlling things such as fuelling, timing, boost, acceleration, deceleration and many more. Some examples of 3D models of some maps are shown.

You will probably be surprised to discover that the vehicle manufacturers often modify the mapping of their ECU’s for marketing reasons, to differentiate between models and specifications for example, with the same engine often being fitted to numerous models of vehicle there has to be a performance difference between their low-specification, regular and “sports” models. This is frequently achieved by de-tuning the cheaper models.
Manufacturers also have to comply with very strict emissions requirements and tests that are performed to meet UK and European testing parameters, these often mean that between 1,700 rpm and 3,000 rpm the engine output is deliberately held-back to pass these tests. Having a negative effect upon both performance and economy.
