#1 Diesel Dyno Tuning in Maryborough
Real Dyno Tuning — Not a Carpark Flash
A bad tune can cost you more than horsepower—it can wreck your engine or transmission if not done right. Whether you’re towing heavy or chasing peak performance, diesel dyno tuning gives you safe, data-driven gains you can trust.
We only use the best when it comes to modifying any vehicle. We have a purpose-built soundproof Dyno cell with the latest technology, Mainline Chassis Dyno, capable of up to 850KW ( 1130hp) and 1700nm ( 1254 Ftlb ) of torque.
Why Dyno Tuning Makes a Real Difference
Modern diesel engines are controlled by complex ECU systems. Without proper testing, a simple “file flash” can leave performance gains unverified and sometimes unsafe.
With dyno tuning at Core Diesel, we can safely optimise your engine while monitoring boost, torque, air-fuel ratios, and engine load.
That means you get measurable improvements you can feel immediately.
Drivers typically experience:
🔧 More usable power and torque for everyday driving
🚚 Stronger, safer towing performance under load
⛽ Improved fuel efficiency on long drives
🛞 Better throttle response for off-road and touring
Most vehicles see 15–30% torque improvements after a properly developed dyno tune.
🚫 No carpark tunes here. ✅ Real dyno tuning. Real results.
At Core Diesel, we’re the only workshop on the Fraser Coast with an in-house dyno, which means your vehicle is tuned under load and monitored in real conditions — not flashed in a carpark and sent on its way.
That difference matters.
When we tune your 4WD or diesel ute, we can measure exactly how your engine performs before and after the tune, making adjustments in real time to ensure safe and reliable gains.
Every dyno tune and ECU remap is:
✔ Tested before and after on the dyno
✔ Custom calibrated to your vehicle and setup
✔ Optimised for power, torque, and drivability
✔ Verified with real performance data
No guesswork. No generic files. Just proper dyno-tested tuning built for Aussie conditions.

More Power, Less Fuel Waste — Pick a package that's right for you
Custom ECU Remap & Exhaust/Throttle Controller
This is the minimum we would recommend for any 4WD all-round daily drivers, who go up the beach occasionally & tows very minimally.
Custom ECU Remap & Exhaust/Throttle Controller/Trans Cooler Upgrade/Scan Gauge
This is the most common package we do for people that like to get away with the van on the back & explore the open & off-road adventures.
Custom ECU Remap & Exhaust/Throttle Controller/Trans Cooler Upgrade/Intercooler Upgrade/Trans Valve Body Upgrade/Scan Gauge
This is for the motivated travellers that get away more often than a couple of times a year &/or have that great trip planned - these are more tailored to suit customer/vehicle needs.

Frequently Asked Questions About Diesel Dyno Tuning
Will dyno tuning damage my engine?
No, our dyno tuning is customised and safely calibrated for your specific vehicle and use. We don’t push limits just to chase numbers.
How much extra power will I gain?
Depending on the setup, most diesel vehicles gain between 15% and 30% more torque and 10% to 25% more kilowatts.
We can also improve performance with ECU remapping by adjusting key settings. This includes fuel injection timing, air-to-fuel ratios, and turbo boost levels.
Will tuning affect my fuel economy?
Yes – properly tuned diesels often consume less fuel under load or highway cruising conditions.
Can you tune modified vehicles?
Absolutely. We regularly tune vehicles with turbos, intercoolers, exhaust upgrades, and more.
Do I get a report showing results?
Yes – you’ll get a printed or digital dyno sheet showing before and after power and torque figures.
Why does my diesel feel sluggish even after mods?
Chances are, your tune isn’t optimised. Dyno testing shows what’s wrong and how to fix it.
Will this improve fuel economy?
Yes—if your current tune is rich or inefficient, a dyno tune balances air-fuel ratios for more efficient burn.
How do I know my tune is safe?
Dyno tuning monitors temps, fuel pressure, and boost live to keep everything in safe limits.
My truck smokes under load—can tuning fix that?
Absolutely. Too much smoke means too much fuel and not enough air. A proper tune corrects this.
Will this damage my engine or shorten its life?
No. When done right, tuning protects your engine by preventing excessive temps or stress.
Will this affect my warranty?
Some manufacturers track tuning changes. If warranty is critical, ask us about safer tuning options.
How long does a dyno session take?
1–4 hours depending on your truck and setup. Come in prepped and you’ll be out the same day.
