Claims without data aren't worth much. Every tune at Core Diesel is developed and verified on our in-house Mainline DynoLog dynamometer, capable of up to 850kW and 1,700Nm. We run your vehicle on the dyno before we touch the calibration, establish a real baseline, then develop and verify the tune under load. You get the before-and-after data sheets.
We're the only workshop on the Fraser Coast with an in-house dyno. That's not just a convenience. It fundamentally changes the quality of the tune. We can measure boost pressure, air-fuel ratio, exhaust gas temperature, and torque delivery in real time and make changes accordingly. A carpark flash can't do any of that.
You leave with before-and-after dyno data sheets. Power gains aren't promises. They're documented numbers.
Real-time monitoring of boost, temperatures, and fuel mixture means we catch problems before they become damage. Generic tunes can't do this.
Dyno runs reveal drivetrain inefficiencies, power loss, and inconsistencies that standard diagnostics miss.
For serious builds, our dyno is capable of handling up to 850kW. We tune everything from modified daily drivers to dedicated performance builds.
Watch a real dyno tune run at our Maryborough workshop.
Contact us to discuss your vehicle and goals. We'll confirm the right approach and book a session.
We run a baseline, assess your vehicle's current state, and develop the tune under controlled conditions.
Post-tune dyno runs confirm the gains. You leave with documented before-and-after figures.
A chassis dynamometer measures power at the wheels under real driving conditions. Our Mainline DynoLog can handle up to 850kW (1,130hp) and 1,700Nm of torque, meaning we can safely test and tune everything from modified 4x4s to high-output diesel performance vehicles.
Yes. Dyno runs reveal power inconsistencies, flat spots, boost leaks, and drivetrain inefficiencies that don't show up on a standard road test or scan. It's one of the most thorough diagnostic tools available.
A street tune is done by feel and limited data logging. A dyno tune is done under controlled, repeatable conditions with real-time measurement of all critical parameters. The results are measurably safer and more consistent.
A standard tune and verify session takes a full day. Diagnostic sessions are typically 2–3 hours.
Our primary focus is diesel, but we do handle selected petrol applications. Contact us to discuss your vehicle.


Core Diesel has been the Fraser Coast's go-to diesel workshop for over a decade. From logbook servicing and major engine rebuilds to ECU remapping and 24/7 mobile callouts, our team of experienced diesel technicians handles it all in-house, using the latest diagnostic tools and equipment, with a commitment to straight-talking service and zero unnecessary upselling.
The only workshop in the Fraser Coast region with an NHVR-approved Brake Shaker Test Unit, a legal requirement for heavy vehicle certification.
Deep knowledge of RAM, Silverado, and F-150 mechanics, rare outside capital cities. Parts sourced, issues diagnosed, jobs done properly.
Every job is documented with photos and video reports so you know exactly what was found and what was done.
All repairs are backed by our workmanship warranty. No hidden costs, no unnecessary work recommended.
"Took my 4WD to these guys when no one else could diagnose and fix it. Issue was found and fixed that day. These guys were recommended by a friend. Couldn't be happier."
Clinton Davis"Video progress the whole service and constant communication so you know what's going on. Seems like a bunch of genuine blokes who love working on cars."
Jordan Francis"Core Diesel have our entire fleet of trucks prioritised and professionally serviced. Always good advice on keeping things in tip-top shape."
