About this remap
Volkswagen Golf 1.6 FSI 115 hp Stage 1 — what changes
The Volkswagen Golf 1.6 FSI 115 hp (2003–) leaves the factory at 115 BHP and 155 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 1.6 FSI 115 hp powertrain (petrol). The result is 130 BHP and 173 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
