About this remap
Ford Focus 1.8i 125 hp Stage 1 — what changes
The Ford Focus 1.8i 125 hp (2004–) leaves the factory at 125 BHP and 170 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 1.8i 125 hp powertrain (petrol). The result is 130 BHP and 180 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
