Hello, at Ebay there is a chip for 25 € to buy. It promises with the MV6 +20Ps, +35 Nm and -0.5 L consumption. Installation should be very easy. So you ask yourself…why not? But does someone have experience with this or a similar chip? What negative consequences could this have in the long term?https://www.ebay.de/…/380115869740 Thanks and greetings.
