Legal reference:

In principle it is strictly forbidden for any intervention to be made on the engine. Such alterations wether of a simple nature, useing a powerchip, or even a much complicated intervention of the ECU, canges the quality of the exhaust fumes and therefor the tax category.Because the car has a certain classification in it's emission tax category, by making any changes could risk a conflict situation with the tax authorities (Inland Revenue)

Therefore it is explicitly noted that the measures descripted here are not suitable for any participation on public roads and highways.
