Photo's from the day at the track with CA-Technologies Mapper and Performance BMW Magazine. The Z4 has an even loader induction noise and boy does it pull more now
The M3 is just amazing, now a real big kick higher up the rev range with those CAMS and ... what an induction noise from the Goke and GuppeM Airboxes. Very happy. Just now waiting on my new rear bumper then done....
Very happy chappy
