Innovative Diesel Performance Services
Having invested over $100,000 into hardware, software, research and development, Just Autos continues to provide proven results time and time again when it comes to our diesel performance services in Australia: custom ECU remapping, common rail and turbodiesel tuning, and performance modifications, upgrades and packages.
With a Just Autos custom ECU remap, EGR functions can be switched off in the ECU, which stops abrasive diesel exhaust gas from being recirculated through your motor. We can also switch off several other DTC (diagnostic trouble codes) that may occur when custom modifications have been carried out.
If you have had an HKS installed and tuned by Just Autos, we will compliment it with custom remapping of the ECU to give you the best of both worlds – maximum power and torque from the piggyback, and no nasty EGR impact.

The Proof Is In Performance
Toyota Performance Services
The 200 Series Land Cruiser is one of Australia’s most sought-after tow vehicles with high outputs in torque, high comfort, and a 6-speed automatic transmission.
We offer upgrades designed for touring and towing, which means improving the drivability and torque while improving efficiency as well. We also have upgrades for the die-hard performance enthusiast with packages capable of making over 350hp at all 4 wheels and over 1000nm of torque. We have options for both PRE DPF & DPF Vehicles, contact us today.

The factory Toyota 70 Series Land Cruiser delivers around 145hp and 350Nm at the wheels — figures that can leave much to be desired, especially for owners who tow or carry heavy loads.
At Just Autos, we offer performance upgrade packages specifically developed for the 70 Series platform. Our entry-level solutions can increase output to over 200hp and 650Nm at the wheels*, providing significantly improved drivability and torque delivery.
With a deep focus on Toyota diesel tuning, we tailor each setup to suit your specific driving needs.
Performance results may vary depending on vehicle condition, setup, and supporting modifications. Fuel efficiency improvements are not guaranteed.

With over 20 years of specialised experience in Toyota diesel performance, Just Autos offers a range of upgrade packages tailored for both the 3.0L 1KD and 2.8L 1GD engines.
Whether you’re after better drivability or increased towing capability, we have touring setups designed to deliver improved torque and responsiveness.

Just Autos uses industry-leading master tuning hardware and software to perform custom remaps of the factory ECU (Engine Control Unit) in your Toyota, tailored to your vehicle’s specific model and specifications.
Our custom tuning process is completed via the OBD diagnostic port, meaning your ECU does not need to be removed or physically modified.
