Abdul brought in his 2019 Mercedes-AMG C43  for a performance tweak on the Bosch MED17.7 ECU . Although the vehicle already had a tune and downpipes installed , it felt a bit laggy. Our professional ECU retune  optimized power delivery, resulting in: +26 kW at the wheels +32 Nm of torque In addition, we installed a switchable burble logic  that activates on Sport and Sport+ modes only , giving the C43 an aggressive exhaust note when desired without affecting daily drivability
