About this remap
DS 4 Crossback 1.2 PureTech 129 bhp Stage 1 — what changes
The DS 4 Crossback 1.2 PureTech 129 bhp (2015–2019) leaves the factory at 129 BHP and 230 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 1.2 PureTech 129 bhp powertrain (petrol). The result is 155 BHP and 271 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
