Bentley Continental GT Speed 6.0 W12 Bi-Turbo 635HP

Remapping Data - Engine Remap Performance and Torque Gains

Remapping the Bentley Continental GT Speed, 6.0 W12 Bi-Turbo 635HP.

A Stage 1 remap on the 6.0 W12 Bi-Turbo 635HP in the Bentley Continental GT Speed lifts power and pulling power in equal measure, taking BHP from 635 to 680bhp (+7.1%) and torque from 820 to 900Nm (+9.8%).

As a turbocharged petrol, there is real headroom here, and this worthwhile gain shows up mainly as a broader, more responsive power band rather than one dramatic jump.

  • Power: 635bhp standard, 680bhp after a Stage 1 remap.
  • Torque: 820Nm standard, 900Nm after a Stage 1 remap.
  • This is a balanced gain: power and torque increase by a similar margin, rather than one outpacing the other.
  • This is a turbocharged engine, which typically means further headroom exists beyond Stage 1 if hardware is upgraded.
  • As a petrol engine, the practical benefit is mainly felt as sharper throttle response and a broader power band.
  • These are Stage 1 figures only, achieved without any hardware changes.

Questions about remapping your Continental GT Speed 6.0 W12 Bi-Turbo 635HP

How much power and torque does a Stage 1 remap add to the Bentley Continental GT Speed 6.0 W12 Bi-Turbo 635HP?

A Stage 1 remap typically takes the Bentley Continental GT Speed 6.0 W12 Bi-Turbo 635HP from 635bhp to around 680bhp, and torque from 820Nm to around 900Nm. This is a worthwhile gain achieved entirely through software, with no hardware changes required.

Is the Bentley Continental GT Speed 6.0 W12 Bi-Turbo 635HP a good candidate for remapping?

Generally, yes: as a turbocharged engine it has the headroom to respond well to a quality remap, and the worthwhile gain shown here reflects that. The main caveats are condition, not the engine itself, a healthy service history, no outstanding fault codes, and (for diesels) a clear DPF and EGR are what actually determine whether this particular car is ready for a remap.

Will remapping affect the warranty on my Bentley Continental GT Speed?

A manufacturer can only void the parts of a warranty that the remap directly affects, not the entire vehicle, under the Consumer Rights Act and EU Block Exemption principles. In practice, on a Bentley Continental GT Speed 6.0 W12 Bi-Turbo 635HP this usually means engine and transmission-related claims are the ones worth discussing with a reputable tuner before booking.

What should I check before booking a remap for my Bentley Continental GT Speed 6.0 W12 Bi-Turbo 635HP?

Before booking, confirm the tuner uses a custom or bespoke file rather than a generic off-the-shelf map, ask whether they do a pre-remap health check, and check service history and mileage on your specific Bentley Continental GT Speed.

What's the difference between a Stage 1 and Stage 2 remap for the 6.0 W12 Bi-Turbo 635HP?

Stage 1 is software-only and is what the figures on this page reflect. Stage 2 builds on that, but on a turbocharged engine like this, Stage 2 usually adds further gains but requires supporting hardware such as an upgraded intake or exhaust, so it is a separate conversation with a tuner rather than an automatic next step.

Will remapping my Bentley Continental GT Speed affect my insurance?

Yes, always, a remap is a modification and must be declared to your insurer regardless of size. Given this worthwhile gain on the 6.0 W12 Bi-Turbo 635HP, expect a likely premium increase, and it is worth getting a quote from a specialist modified-vehicle insurer before booking the remap itself.
