RAM Truck Upgrades Fraser Coast

More Torque, More Towing, More Confidence

Built for Power. Tuned for Australia.

Your RAM truck is a beast—but it wasn’t built with Aussie roads, heat or towing in mind. At Core Diesel, we help RAM owners unlock real-world performance with ECU tuning and performance upgrades tailored for Australian conditions.

Whether you’re driving a RAM 1500 for work, touring with a 2500, or hauling serious loads with a 3500, we provide the tools and expertise to make your truck work smarter and harder.

Located in Maryborough and trusted across the Fraser Coast, Core Diesel delivers proven performance mods, safe tuning, and no-nonsense service.

Why RAM Drivers Choose Core Diesel

Improved Towing Confidence – More torque means safer, smoother towing up hills or on highways.
Better Fuel Efficiency – Get more from every tank, especially under load.
Smoother Driving – No more turbo lag or sluggish take-offs.

We understand RAM trucks. We don’t just remap—we tune for how you actually drive in Australian conditions: heat, dust, distance and weight.

Such wonderful people to do business with. They did an excellent job of finally finding out what our problem was & fixed it. So glad to finally have our car running smoothly as it should have been a long time ago.

Core Diesel Maintenance recently completed repairs on our truck. They were meticulous, kept us updated every step of the way & nothing was a problem. We can highly recommend them & we will be taking all our trucks to them in the future.

Some of the best service I’ve had in years! The amount of communication and follow-up calls was outstanding and the service provided in the end could not have been better we are Very happy with this company and will be using them for all repairs and servicing.

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 with the service. Will be using their services again.
