Hello and good evening! I’m new here and would like some advice. Tomorrow at 10.00 am I have an appointment at the company Racechip to install a Racechip Pro Chiptuning in my Phaeton… Here the company I know a little about Chiptuning and have just found this link on the internet: eBay . Now my question: What is the difference with these chips? It is in both cases a Racechip. Since the chip in eBay is very cheap, I am suspiciously g I don’t want to spend so much. Can someone help me? – I’m unsure… Lars, I’m not sure if I’m going to be able to buy a new car.
