About this remap

Bentley Arnage 6.8 V8 Twin turbo 500 bhp Stage 1 — what changes

The Bentley Arnage 6.8 V8 Twin turbo 500 bhp (1998–2009) leaves the factory at 500 BHP and 1001 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 6.8 V8 Twin turbo 500 bhp powertrain (petrol). The result is 560 BHP and 1085 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
