About this remap

Mercedes Benz A Class A180 BLUE-CY (1.5) 109 bhp Stage 1 — what changes

The Mercedes Benz A Class A180 BLUE-CY (1.5) 109 bhp (2014–2018) leaves the factory at 109 BHP and 260 Nm of torque. Manufacturers deliberately detune this engine to separate it from more expensive variants in the range — a Regal Tuning Stage 1 calibration safely recovers that headroom through the ECU alone: no hardware changes, no dyno risk, fully reversible.

Fuelling, boost pressure, ignition and torque limiters are optimised within the safe tolerances of the A180 BLUE-CY (1.5) 109 bhp powertrain (diesel). The result is 140 BHP and 325 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
