Tests carried out by automotive journalistshave all highlighted the reduction in diesel consumption which is induced by the use of P-Tronic tuning boxes. If you consume less, you emit less CO2 and so you pollute less. It's logical. This is all the more true as the reprogramming of the injection as effected by P-Tronic chip tuning in no way alters the contents of the exhaust gas.
Furthermore, Increasing our fleet - and therefore harmful emissions - is incessant. The acquisition of a chip tuning for reducing the pollution associated with this phenomenon has become a civic act.
