4x4 Chip upgrade for Land Rover and Rover
This chip is an electronic unit wich fits inside the engine management control unit and stores the fuelling information required to run the engine from idle to maximum power.
We have read the standard chip and modified the fuelling information to suit the day to day driving requirements and towing needs. As a result of the Chip upgrade the vehicle is more responsive and more relaxing to drive.

The Freelander chip upgrade provides:
  • An increase in power of 27% = 120 BHP
  • An increase in torque of 30% = 200 lb/ft
  • Standard power of 95 – 97 BHP
  • Standard torque of 155 lb/ft

The Rover 200 series SDI chip upgrade provides:

  • An increase in power of 27% = 125 BHP
  • An increase in torque of 30% = 200 lb/ft
  • Standard power of 105 BHP
  • Standard torque of 150 lb/ft

The Land Rover Defender TD 5 chip upgrade provides:

  • An increase in power output from 126 to 150 BHP
