Hi all, May I seek your advice if I should go to Monster Tune or Dynotechnica for ECU tuning? After the ECU tuning, I was told that the horsepower will increase, as such do I need to install anything in the car to support the enhance performance? Eg. better braking kit, exhaust system and etc... I am also looking for body parts modification and appreciate contact for good workshop who can advise me on this matter. Thank you all in advance.

Hi all, I am currently driving a C180 Avantgarde and found that there is a clicking sound (lasted 1-2 seconds) when the gear is shifted from D4 to D5, I wonder if anyone has experience the same issue? Thank you all in advance.
