A gain of 25 - 50 horsepower, increased throttle response and increased efficiency.
Our performance chips have been specifically designed to allow your Defender or Discovery fitted with a Td5 to operate at optimum levels to suit Australian conditions (including fuel quality).

Defender intercooler - large capacity upgrade. (Discovery intercoolers available.)
The intercooler installed in your Defender would be more than adequate in Europe but Australian conditions, particularly the heat, limit the potential of your vehicle.
This larger capacity intercooler fits neatly into the convenient space left by the manufacturer to allow upgrades.
Tech Fact: Turbo engines use air forced into the combustion chamber to be mixed with fuel. Air expands when it is hot so therefore if the air is cooled more can be forced into the chamber. This increases the efficiency of the engine using the fuel more economically giving better power, performance and consumption.

From 2½" to 3" exhaust systems
The exhaust outlet manifold is 3" which is reduced to 2½" to the exhaust pipe and muffler.
By continuing the 3" system right through and adding a large capacity muffler the engine clears the exhaust fumes faster and runs much cooler. The engine runs more efficiently and increases the horsepower. (Software or ECU upgrades are recommended.)
We have full stainless systems available. Do it once and do it properly.
Note; Combine this exhaust system upgrade with a larger capacity intercooler and the engine runs even more efficiently.

TD5 DPL modified injector harness
Due to the extreme heat oil in forced through this harness causing electrical failure.
We have modified this harness to totally eliminate this problem. (See our other intuitive modifications to these great TD5 engines.) TD5 mods
