About the remap
Stage 1 chip tuning for the BMW 1 serie 135i - N54 306hp increases power from 306 to 363 hp (+57 hp, +19%) and torque from 400 to 510 Nm. Turbocharged petrol engines respond exceptionally well to ECU optimization – adjusting ignition timing, boost pressure, and fueling maps unlocks the hidden potential built in by the manufacturer.
