Overview

The third generation Continental GT W12 uses the most developed version of Bentley’s twin turbo W12 and a modern torque based Bosch control system. It is already very capable from the factory, so good tuning is about extending the torque band and sharpening response without upsetting the grand touring character. The platform rewards careful calibration more than aggressive peak chasing. Stage 2 adds a meaningful lift in the upper load range when combined with freer downpipes and better thermal control.

Key Features

  • advanced torque model strategy
  • huge low rpm reserve
  • seamless grand touring delivery
  • stronger upper load pull
  • heat management important on Stage 2

  1. Remove the ECU from your vehicle (refer to your workshop manual for location and procedure)
  2. Package securely and ship to AMT Tuning at the address below
  3. AMT will read your stock file and flash your custom tune directly on the bench
  4. Turnaround is typically 3–5 business days from receipt
  5. Reinstall the returned ECU — the tune is active immediately on start-up
