I got my Zetti back on Friday after the compressor installation. The first exits yesterday and today were great. I’m really excited, I can’t believe what happened to the previously “braven” Z4. He drives very confidently like a suction cup with more engine capacity and PS. Now that’s what I missed in the 3.0 l series! The tuning really succeeded. The performance development is very harmonious. Even at low speeds is plenty of torque there, Cozy with 60 km/h in the 6th gear rolling is no problem – no jerking, nothing. At higher speeds the post office goes off. On the highway the acceleration of 100-200 feels like before – felt – from 0-100. At this point cordial thanks to the company Infinitas and above all the very nice and very competent care of Frank Sonneborn, Fa. Sonneborn in Altena. Greeting Prian
