Your Chevy was tuned for American conditions, not Australian roads, heat, and towing demands. We unlock the performance that's already in your truck.

Most Chevys leave the factory tuned for American fuel, emissions rules, and road conditions, not the long distances, high heat, and heavy towing we deal with in Australia. At Core Diesel, we specialise in Chevy performance upgrades tailored for Australian drivers, based in Maryborough and servicing the Fraser Coast.
Whether you're hauling a caravan, towing on the job, or want smoother performance every day, we have proven, safe solutions to unlock your truck's potential. More usable torque, improved throttle response, better fuel efficiency, and enhanced towing performance.
Custom tuning that brings your engine to life without over-stressing components. More torque, smoother power delivery, and improved fuel economy, all within safe limits.
Heavy-duty springs, airbags, and shock upgrades keep your Chevy level and stable when towing caravans, boats, or work trailers.
Performance stainless exhausts and high-flow air intakes reduce backpressure and improve airflow. Optional intercooler upgrades available.
Every tune is designed for Australian heat, dust, distance, and load, not North American conditions.
We can return your ECU to stock settings at any time if needed, such as when selling the vehicle.
Tell us your model, how you drive, and what you want from your truck. We'll recommend a proven performance package.
Flexible bookings to suit your schedule. Most upgrades are completed in one to two days.
Feel the difference straight away: more pull, better response, and smoother power delivery.
Not when done professionally. We work within safe tolerances and adapt the tune to your specific model, with no aggressive overboosting or shortcuts.
Most customers see 15–30% torque improvement, smoother power delivery, and fuel savings depending on driving style and load.
Some upgrades may affect certain aspects of a new vehicle warranty. We'll guide you through what's involved for your specific situation.
