Toyota Diesel Performance Specialists

Enhance Your Toyota Diesel's Performance

Unleash the true potential under your hood with our custom diesel performance tuning services – tailored specifically for common rail diesel and turbodiesel Toyota engines. As Australia’s premier Toyota common rail and turbodiesel tuning experts, Just Autos will have everything you need to see improved performance from your diesel, and then some – just visit our workshop on the Sunshine Coast for helpful advice and performance upgrade opportunities unique to your situation, as well as Toyota model and spec.

As Toyota owners ourselves, we know what it’s like to feel limited by factory settings and manufacturer specifications. The diesel Toyota engine is renowned for its ruggedness and durability, but we know they’re capable of so much more. Book your Hilux, Prado, or Land Cruiser in to our workshop and our diesel performance experts will work closely with you to understand your performance needs. 

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.

With a Just Autos custom remap, EGR functions can be switched off in the ECU, which stops abrasive diesel exhaust gas 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.

And 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.

We have a variety of performance upgrades, packages and services available

Toyota 200 Series Land Cruiser

The 200 series Land Cruiser platform 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. DPF options are available.

Toyota 70 Series Land Cruiser

Anyone who owns a 70 Series Toyota Land Cruiser knows that the power output is something to be worked on – with only 145hp and 350nm at the wheels, it’s no better than the majority of light vehicle 4wds on the market with smaller capacity engines.

At Just Autos, we can change that disappointing output figure into something capable of towing heavy loads without stressing the engine; with base packages producing over 200hp and 650nm at the wheels, we have every option covered for your 70 Series. DPF options are available.

Toyota Hilux and Prado Tuning & Upgrades

With over 15 years of experience and knowledge on the Toyota platform, we have multiple options for the 3.0 1KD and also the 2.8 1GD engine.

We have packages available for every person in mind, with a full touring setup to improve towing efficiency and torque, to a full package capable of making well into the 300hp range. DPF options are available.

ECU Remapping for Toyota Diesels

Just Autos have the master tuning hardware and software required to complete custom remaps of the factory ECU (Engine Control Unit) in your Toyota, specific to your model and spec. 

The Just Autos custom remap is performed via the ODB diagnostic port. This means that your ECU does not need to be removed or tampered with.
