Why Core Diesel Is the Fraser Coast’s One-Stop Shop for American Trucks
View this post on Instagram
If you drive a RAM, Chevy Silverado, or Ford F-150 on the Fraser Coast, you already know one thing: not every workshop is equipped to work on these trucks properly.
They’re bigger. Heavier. More complex. And built for American fuel, roads and regulations — not Aussie heat, long hauls, or serious towing.
That’s exactly why Core Diesel exists.
Based in Maryborough and trusted across the Fraser Coast, we’ve built our workshop, tooling and processes specifically to support American trucks the right way. No guesswork. No generic tunes. Just safe, proven solutions that work in real Australian conditions.
American Trucks Need a Specialist — Not a General Mechanic
RAMs, Chevys and F-150s aren’t just oversized utes. They’re closer to light-duty trucks, with:
- Different engine management systems
- US-spec diagnostics and software
- Heavy-duty transmissions and drivetrains
- Larger cooling, braking and suspension systems
A workshop that’s great with small diesels or standard 4x4s can quickly come unstuck with American imports.
At Core Diesel, American trucks aren’t an afterthought — they’re a core part of what we do.
What Makes Core Diesel Different for RAM, Chevy & F-150 Owners
1. Proper Diagnostics for US-Spec Vehicles
We’ve invested in advanced diagnostic tools that actually communicate with American truck ECUs.
That means:
- Accurate fault finding
- Correct live data logging
- No “try this and see” repairs
If there’s an issue, we find the real cause — not the symptom.
2. In-House Dyno Tuning — Not Generic Files
This is where most workshops fall short.
We don’t load copied tunes or handheld files. Every American truck we tune is:
- Inspected before tuning
- Tuned specifically for Aussie fuel
- Tested and verified on our in-house dyno
This allows us to control:
- Torque delivery for towing
- Exhaust gas temperatures (EGTs)
- Boost and fuel safety margins
The result? Stronger, smoother performance without sacrificing reliability.
3. ECU Remapping Built for Aussie Conditions
Factory American tunes are conservative — and not designed for our conditions.
Our ECU remapping delivers:
- 15–30% torque gains (model dependent)
- Better throttle response
- Reduced lag under load
- Improved drivability when towing
All while staying within safe limits for your engine and transmission.
This is diesel tuning on the Fraser Coast, done properly.
4. Supporting Upgrades That Actually Make Sense
Power without support causes problems. That’s why we offer the full package, including:
- Exhaust and intake upgrades
- Intercooler improvements
- Carbon cleaning for short-trip vehicles
- Suspension and towing support mods
- NHVR-approved brake testing (Fraser Coast only)
Everything works together. Nothing is thrown on “just because”.
Servicing, Maintenance & Long-Term Reliability
We don’t just tune American trucks — we keep them healthy long-term.
Our preventative approach includes:
- Full inspections before upgrades
- Honest reporting with photos
- Clear advice on what matters now vs later
- Fleet and business-friendly scheduling
For regional drivers and towers, downtime costs money. We get that.
Real-World Driving, Real-World Results
Whether you’re:
- Towing a caravan from Maryborough to Hervey Bay
- Hauling gear inland toward Bundaberg
- Running a RAM or Silverado as a work truck
Our upgrades are designed for heat, dust, distance and load — not showroom figures.
That’s why our customers say their trucks feel:
- More confident under load
- Smoother to drive every day
- Easier on fuel over long runs
FAQs
Do you only work on diesel American trucks?
Diesel is our specialty, but we also work on petrol variants like HEMI and EcoBoost models.
Is tuning safe for towing?
Yes — when done correctly. Our tunes prioritise torque at lower RPM and EGT control.
Can the tune be reversed?
Absolutely. We can return your ECU to stock at any time.
Do you service outside Maryborough?
Yes. We work with customers across the Fraser Coast including Hervey Bay, Tiaro, Howard and surrounds.
