About this remap

Bentley Continental GT Speed 6.0 W12 TwinTurbo 650 hp Stage 1 — what changes

The Bentley Continental GT Speed 6.0 W12 TwinTurbo 650 hp (2021–) leaves the factory at 650 BHP and 900 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 6.0 W12 TwinTurbo 650 hp powertrain (petrol). The result is 690 BHP and 1000 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
