greetings pop pickers
i have a disco 2 td5 and have just bought a caravan, after two outings i feel i need more power from the engine, not necessarly more speed, the landrover guy who does my servicing says that there are plug and forget gizmo,s that take care of all the necessary remapping without the need for much actual mechanical intervention, i know absulutly nothing about this and would kindly ask for guidance from those in the know.
thanks
tony
