Performance Chip

Having a performance chip is a well known and cost effective tuning method. The chip is installed in the engine control unit. The purpose of these chips is to alter the engine timing allowing the engine to develop more horse power and torque. J and G can install this device in your Land Rover easily.

Air Filter

Air filters can also upgrade the power of a Land Rover. This is only possible if your mechanic ensures that clean air enters the engine combustion chamber. Other ways to upgrade the power is by adding a cold air intake, which cools the air before it enters the engine. At J and G we install the most efficient air filters that are the best fit for your Land Rover.

Weight Reduction

J and G Automotive in San Rafael can reduce the weight of your Land Rover for increased performance. This increases the speed of your Land Rover. When tuning the following items can be removed:

  • Spare Tire and Jack
  • Air Conditioning System
  • Speakers
  • Door Insulation Panels

All this is done to ensure that the Land Rover gains greater acceleration and top speed.


We provide breathing modification (intake and exhaust) tuning services, internal engine tuning modifications, re-bores, port matching, camshafts, fueling and more.

Sport Computer


We can tune your Land Rover with a sports computer to change the timing characteristic of the engine. We offer sport computer tuning that is matched to the engine, driving style, fuel choice and car condition. Sport car tuning ensures massive power gains and better fuel economy. With sport car truing it's important that the driver keep the engine at peak condition, for example, changing the plugs regularly.
