Dinan Engine Software raises the factory rev-limiter by 150 rpm (8400 rpm maximum), endowing the V-10 with a broader power band and greater road speed potential in each gear.

  • It removes the top speed governor, enabling the cars to attain their ''natural'' top speed; and the V-10s WILL pull right to red-line in top gear!
  • It speeds up throttle response, providing a sportier feel and improved modulation capabilities.
  • Dinan's software also provides re-calibration of the factory ''torque limiting'' programming, ensuring that maximum power is available under varying driving conditions.
