About this remap

Mercedes CLC 200 CDI (2.1) 122 hp Stage 1 — what changes

The Mercedes CLC 200 CDI (2.1) 122 hp (2004–) leaves the factory at 120 BHP and 270 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 200 CDI (2.1) 122 hp powertrain (diesel). The result is 168 BHP and 350 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
