About this remap

Bugatti Veyron 8.0-W16 1001 hp Stage 1 — what changes

The Bugatti Veyron 8.0-W16 1001 hp (2005–) leaves the factory at 1001 BHP and 1250 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 8.0-W16 1001 hp powertrain (petrol). The result is 1201 BHP and 1500 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
