About this remap

BMW 5-serie 25i 192 hp Stage 1 — what changes

The BMW 5-serie 25i 192 hp (1995–) leaves the factory at 192 BHP and 250 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 25i 192 hp powertrain (petrol). The result is 200 BHP and 260 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
