Machine Translation: „Absolute satisfaction. The engine runs quieter and smoother and consumption was reduced by 1 liter / 100km. I’m not entirely sure about the overall performance. The reaction to the gas is much faster – the turbo switches earlier, so at 100 km / h I will probably be a little earlier than before the modification. Opel Astra 2.0 CDTI – 121 KW before modification ”
