Dyno Tuning

Dyno tuning is the most accurate way to tune a diesel engine properly.

It allows us to measure real power, torque, air-fuel ratios, boost pressure, and engine behaviour under load.

By tuning your vehicle on our in-house dyno, we can:

Identify factory limitations and inefficiencies
Adjust fueling and boost safely
Improve throttle response and torque delivery
Confirm gains before and after tuning

Every dyno tune is vehicle-specific and load-tested, ensuring smooth performance both on and off the road.

ECU Remapping

ECU remapping adjusts the factory engine control software to unlock safe, usable performance.

This improves how the engine delivers power, especially under load or when towing.

A professional diesel ECU remap can:

Increase low- and mid-range torque
Improve throttle response
Reduce gear hunting when towing
Improve overall driveability

Our ECU remaps are written specifically for your vehicle and setup, not downloaded generic files.

Safety margins, engine longevity, and reliability are always prioritised.

ECU Remapping

Exhaust Upgrades

A factory exhaust system often restricts airflow, limiting performance and efficiency.

Upgrading the exhaust allows the engine to breathe more freely and reduces exhaust gas temperatures.

Benefits of a diesel exhaust upgrade include:

Improved torque delivery
Lower exhaust back-pressure
Better fuel efficiency under load
Enhanced engine longevity

We supply and fit exhaust systems matched to your vehicle, tune, and usage.

Exhaust Upgrades

Injector Upgrades

Fuel injectors control how precisely fuel is delivered into the engine.

As power demands increase, factory injectors can become a limiting factor.

Injector upgrades may be recommended when:

Increasing power beyond factory limits
Supporting larger turbo or exhaust upgrades
Improving fuel delivery consistency
Reducing smoke while increasing torque

We assess injector condition, flow requirements, and tuning goals before recommending any upgrade.

I recently had my BT-50 fully modified through EliteTune and couldn’t be happier with the result. During my visit, they handled everything — exhaust, tune, lift kit, plus a full tyre and rim package — all in one go, which made the whole process super convenient.The quality of the work is excellent, and the difference in performance and overall look of the vehicle is unreal. You can tell they take pride in what they do and pay attention to the details.The crew are also very good — easy to deal with, knowledgeable, and happy to answer any questions along the way. They made the whole experience smooth from start to finish.Highly recommend EliteTune to anyone looking to upgrade their vehicle. I’ll definitely be sending people their way.

Got my 80 Series tuned and serviced by Elite Tune and honestly couldn’t be happier. The difference is night and day. throttle response is way sharper, pulls harder through the rev range, and just feels way more alive to drive. It used to feel a bit sluggish, especially towing or going up hills, but now it handles it effortlessly.They really know their stuff too. Rickey was so polite and was to understand as he took the time to explain everything properly and made sure the tune suited how I actually use the car not just some generic setup which other shops do. You can tell they care about doing it right, not just rushing jobs through.Surprisingly it came with a bonus too as my fuel economy even improved a bit and the motor just runs smoother overall. Easily one of the best mods I’ve done to the 80.If you’re thinking about getting a tune, don’t even hesitate. Elite Tune absolutely delivered if i could give other 5 stars i would!

Our Diesel Tuning Process

We follow a structured, proven process to ensure safe results and consistent performance.

Initial vehicle assessment: To inspect condition, check fault codes, review modifications, and understand how the vehicle is used
Baseline dyno run: To measure current power, torque, and engine behaviour and confirm the vehicle is healthy before tuning
File extraction and custom ECU calibration: We pull the file from your vehicle’s ECU, modify it to suit Australian conditions and your specific setup, adjusting fueling, boost, throttle mapping, and torque control
File reinstall and dyno validation: The modified file is put back in and we run the dyno again, checking AFRs and confirming smooth power delivery and safe operating temperatures
Final checks and road testing to verify real-world performance: Including confirming your new horsepower, torque gains, and that your rev range has come down as expected — before the vehicle is returned
