My 2014 MXU450i acceleration run to 60kph. Has Speedwerks exhaust, T-Map mod and Airdam stage 1 machined primary pulley set. Also running 25" Carlisle radials that are around 1.1" taller than stock and about 12lbs. heavier for the full set. Speedometer is a little off so I figured 36mph would be 60kph or more.
