Welcome to AVO 4x4!

AVO Australia has been building high performance turbocharged vehicles, turbocharging n/a vehicles, and pumping up turbo-diesels for over 38 years. Our mission is not only to make your 4x4 Incerease power, but to do it reliably

We accomplish this through a blend of tried and trued performance parts that have seen testing in the harshest condition throughout the world combined with cutting edge research and development for the latest in performance enhancements. Some of our latest products include the AVO DBW Throttle controller and the AVO DFC. 

The AVO Diesel Fuel Controller (DFC) is a plug and play unit the interrupts fuel rail input signals to the ECU and modifies these signals before sending on to the ECU. The ECU then updates its output to the fuel system with a subsequent increase in engine power. The factory setting on the unit can provide up to a 15% increase in peak torque with the same or better increase in peak Horsepower. 

The AVO DFC is designed and manufactured in the AVO facility and has been designed by our resident Electronics Engineer, incorporating AVO's 30 years of Turbocharger experience on both petrol and diesel engines. 


The AVO DBW Throttle Controller allows you to re-map your throttle inputs to the throttle body controller, giving you full control over it’s behaviour.

You may have noticed with your DBW car that the position of the gas pedal doesn’t necessarily correspond to the throttle response. This is because the factory settings are a non-linear map that decides what’s optimal for their needs, not yours. The AVO DBW Throttle controller brings back that control over your car.

A testimonial from one of our customers:
After many years driving petrol 4 wheel drives towing anything from 6 X 4 trailers to race cars and caravans, I finally succumbed to buying a Diesel. It is a 2.5 litre turbo Kia Sorento and I am very happy with it. Anyone that has moved from petrol to diesel though will no doubt lament missing the feeling the petrol gives you of having untapped power under your foot. The diesel on the other hand has far more torque but it is at lower revs and a different driving style is required.

To overcome this difference, I fitted an AVO DFC Fuel Controller and the improvement is very noticeable. The engine has more power right through the range and it has smoothed out the peak in performance that I felt in the Sorento where it appeared to have strong torque initially and then died off. It was particularly noticeable towing my caravan where I used to need a lot of courage to pull out and pass something like a Road Train in Northern Territory but now that is no longer a problem.

To put it to the test I did some timing runs of 0-100kph on a long quiet road and was quite surprised. With the caravan on, the time was 2.8 seconds better with the AVO DFC installed and without the van it was 1.9 seconds better. This makes getting out on the highway for holidays much safer and I feel a lot more comfortable that I have a good amount of that lost power back under the foot.

Anyone looking for a simple bolt on option to improve the performance of their Common Rail Diesel engine should seriously consider the AVO DFC Fuel Controller. Money very well spent in my opinion."
