Just Autos in Tasmania.
Toyota diesel tuning and performance upgrades, fitted and dyno tuned at our workshop in Legana, just north of Launceston.
Who Just Autos are.
Just Autos started more than 16 years ago as a one-man workshop in Nambour. It's now a Sunshine Coast business with 16 locations around Australia.
They only do performance upgrades for Toyota diesels. They don't work across every make on the road, so these engines and gearboxes are what they know.

Just Autos tuning for each Toyota.
What's involved on each model we fit at Legana, for owners in Launceston and across Tasmania.
LandCruiser 300 tuning
FJA300, 3.3 litre twin-turbo V6 diesel, 2021 onwards. It's a strong engine that ends up working hard with a van behind it and a touring load on board. The work is about throttle response, smoother gear shifts and keeping temperatures down when towing, using an ECU remap or multi-mapping, intake pipe, airbox, exhaust, heat exchanger and sump.
LandCruiser 200 tuning
VDJ200, 4.5 litre twin-turbo V8, 2008 to 2021, before and after DPF. Towing is the usual reason owners come in. A transmission lock-up reduces slip with a load on, alongside an ECU remap or multi-mapping, intercooler and fan kits, exhaust and airbox.
LandCruiser 70 Series V8 tuning
VDJ76, 78 and 79, 1VD-FTV 4.5 litre twin-turbo V8 manual, before and after DPF. Just Autos describe the factory tuning as conservative, and these get worked hard towing and touring. The work includes an ECU remap or multi-mapping, a clutch upgrade to suit, exhaust, airbox, intercooler fan kit, turbo and injectors.
LandCruiser 70 Series 2.8 tuning
GDJ79, 1GD-FTV 2.8 litre four-cylinder automatic, 2023 onwards. Tuned especially for towing and off-road work. A lock-up kit cuts transmission heat and slip under load, alongside an ECU remap or multi-mapping with a tow mode, exhaust, airbox and intercooler fan kit.
Toyota Hilux tuning
N80 and N70, 2.8 and 3.0 litre. Stronger towing and sharper throttle response are what most owners are after. A lock-up reduces transmission slip on autos, and on manuals a heavy-duty clutch deals with factory clutches that slip under more power. There's also an ECU remap or multi-mapping, exhaust, airbox, intercooler, turbo and injectors.
Toyota Prado 250 tuning
Prado 250 Series, 2.8 litre. The aim is better towing and a smoother, more responsive drive. That comes from an ECU remap or multi-mapping, performance exhaust and airbox, checked on the dyno.
Who it suits.
Towing
A van, boat or trailer on a long hill is where a standard diesel feels it most. Just Autos tune for drivability and torque, so the vehicle pulls the load more easily.
Touring
A fridge, water, recovery gear and a full tank all add up. The work is about how the vehicle responds with that weight on board, over a long day behind the wheel.
Everyday driving
You don't need to tow to notice it. Just Autos describe the result as a smoother, more responsive drive, and you feel that pulling out into traffic.
What we fit.
What suits your Toyota depends on the model and how you use it. Just Autos will go through that when they quote.
ECU tuning
A custom remap goes in through the OBD diagnostic port, so the ECU doesn't have to come out of the vehicle.
Multi-mapping
An optional extra on top of a remap. You change between driving maps from inside the vehicle, with the controls depending on the model, so it can be set up one way for towing and another for every day.
Transmission tuning and lock-up
Tuning changes how the automatic behaves with the extra torque. A converter lock-up stops the torque converter slipping when it doesn't need to, which cuts heat on long pulls.
Exhaust
A freer exhaust helps the engine breathe as the power goes up.
Intercooler
More power means more heat. A bigger intercooler cools the air going into the engine, which matters most when you're working it hard.
Clutch
On a manual, the extra torque can be more than the standard clutch was built to hold. An upgraded clutch is made to take it.
We don't sell Just Autos parts over the counter, but you can pick up Just Autos 5W-30 engine oil from us any time.
From quote to driving it home.
The quote
Your request goes to Just Autos. They ring you, talk through how you use the vehicle and what suits it, and give you the price. Once you've gone ahead, the work is booked in with us at Legana.
On the dyno
We run the vehicle before we start for a baseline, do the work, then run it again after the tune.
Picking it up
You take the before and after home on paper, and we go through it with you.
Just Autos questions.
Where can I get Just Autos in Tasmania?
At CP Performance, 5 Wrankmore Court, Legana, about 15 minutes north of Launceston. We're the authorised Just Autos distributor in Tasmania.
Which Toyotas do you do?
The LandCruiser 300 (FJA300), 200 (VDJ200), 70 Series V8 (VDJ76, 78, 79) and 2.8 (GDJ79), Hilux (N80, N70) and Prado 250. See your model on the Just Autos website.
What packages are there?
Just Autos keep their packages, specs and figures current on the Just Autos website, where you can also build one.
How do I get a quote?
Use the Request a quote button. It goes to Just Autos, who ring you directly. The work is then done here in Legana.
Does my vehicle have to go to the mainland?
No. The work is done here in Legana, so your vehicle stays in Tasmania.
Does the ECU have to come out?
No. A Just Autos remap goes in through the OBD diagnostic port, with the ECU left in the vehicle.
What's the difference between a remap and multi-mapping?
A remap gives the vehicle one tune. Multi-mapping is an optional extra on top that gives you several, and you change between them from inside the vehicle.
How much power will I get?
Just Autos publish the figures for each vehicle on the Just Autos website. Your result depends on the vehicle's condition, its setup and what else is fitted, which is why we run yours on the dyno before and after.
Will it use less fuel?
It might, but nobody can promise that. Just Autos don't guarantee fuel savings, and how you drive and what you tow will make the biggest difference.
Will it affect my factory warranty?
It can. Manufacturer warranties may have limits on modifications, so it's worth checking before you go ahead. Just Autos can take you through that, and their own warranty options, when they quote. There's more on the Just Autos website.
How long will you need my vehicle?
That depends on the work. We'll tell you when you book it in at Legana.
Can you service it afterwards?
Yes. Once we've done your upgrade we're happy to service the vehicle too. If something needs a look later, it comes back to us.
