When using the appropriate software connected towards on-board computer engineers from the Irvine they can improve engine performance without major modifications towards physical layer of the actual engine. This is called ECU remapping. In some cases, it is also possible to obtain better results in Ecologically driving, which is simply a reduction in fuel consumption. Sometimes it involves, unfortunately, with less durability on the engine, because manufacturers do not necessarily foresee modifying parameters. The data after changing the motor parameters may lead to engine damage, so you should keep this planned and have common feeling.
