This is how our performance tuning process works

  • Firstly, we connect your VDJ70 Land Cruiser to our testing equipment to read important performance indicators such as air-fuel ratio, boost pressure, tachometer speed and RPM.
  • Then, we run your vehicle on our dyno which replicates different road conditions, allowing our technicians to get a baseline measurement of your vehicle’s current performance before any tuning takes place.
  • Our experienced technicians will then make adjustments and modifications to your Land Cruiser’s components for optimal performance.
  • After the upgrades are completed, we run your vehicle on the dyno again to get an after-tune readout, which is then compared to the baseline measurement to gauge the performance improvements achieved.

  • Most Diesel cars sold in Australia over the last ten years, including the Toyota Landcruiser, have had their performance reduced by the factory. There are many reasons for this, which we have explained in an article.
  • The original setup of the Engine Control Unit (ECU) reduces the torque and power of diesel cars by 15% to 25%.
  • Torque is important for diesel engines as it provides a lot of pulling and towing force at low RPM. In contrast, petrol engines generate more force at higher RPM, where the power output is highest, because they don’t have as much torque.
  • Diesel engines use less fuel overall than petrol engines because engines burn more fuel at higher RPM.



  • You may have noticed that your TOYOTA LANDCRUISER becomes noticeably slower when you turn on the air conditioning. This is because the air conditioning system requires power to run, and that power is provided by the engine. 
  • Many Toyota drivers feel frustrated while driving with the air conditioning on because a simple overtaking manoeuvre can become a nightmare, and pressing the accelerator fully is a natural response when they feel their Toyota is not performing as expected.
  • This is the reason a diesel engine struggles to complete an overtake even on a full throttle because it’s designed to provide strong pulling and towing force at mid-range RPMs (2000-4000). 
  • This becomes particularly problematic when driving on gently sloping roads with a medium load onboard, leading to unsafe driving conditions and increased fuel consumption.
  • To address this issue, we offer an ECU Remap that can add an extra 32 horsepower of power and 16% more torque (69NM) to your 70 Series TOYOTA LANDCRUISER. This results in a much more responsive and safer car that can handle overtaking and challenging terrain with ease.


  • Having more torque means that your car can generate more pulling and towing force, which requires less throttle to move the vehicle. This results in overall fuel savings.
  • Based on our calculations, we estimate that the average TOYOTA LANDCRUISER driver can save around 952 litres of fuel every 40,000 kilometres driven after getting our ECU Remap. This also leads to a reduction of approximately 2551 kilograms of CO2 emissions in the atmosphere for your Toyota over the same distance.
  • These are significant savings that not only benefit the environment but also your wallet in the long run.
