Hi, yesterday my rims were put on it and wanted to register my chip from MTM right at the Tüv acceptance. The rims were registered without problems but the chip was not because of the HMS exhaust system. I had installed the HMS system before the chip. I got an expert report on the system quite normal, and a ride and stand measurement was also carried out at that time (dB measurement). Everything in the green area. So and now the Tüv says, they have to use the chip a new dB measurement I could have had an Eisenmann end pot. What’s the problem now exactly? To the KW chassis! I wanted to put down a little bit at the back and at the front. There’s nothing going down at the back, it’s already up to the stop. And it could go down! What can you do there? And at the front you couldn’t move anything else to screw down. All sides are solidly calcified or anodized or whatever you call it. I could go crazy! Greetings Gianni
