About this remap

Mercedes Benz CLC 180K 140 bhp Stage 1 — what changes

The Mercedes Benz CLC 180K 140 bhp (2008–2010) leaves the factory at 140 BHP and 220 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 180K 140 bhp powertrain (petrol). The result is 160 BHP and 247 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
