Chevy Truck Upgrades Fraser Coast

Boost Torque, Towing & Throttle Response with Core Diesel

Your Chevy truck wasn’t built to just look good – it was built to work. But straight from the factory, most Chevys are tuned for American fuel, emissions rules, and road conditions – not the long distances, high heat, and heavy towing we deal with in Australia.

That’s where Core Diesel comes in.

Based in Maryborough and servicing the Fraser Coast region, we specialise in Chevy performance upgrades tailored for Australian drivers. Whether you’re hauling a caravan, towing on the job, or just want smoother performance every day, we’ve got proven, safe solutions to unlock your truck’s potential.

Why Settle for Stock? Get More from Your Chevy

From sluggish take-offs to poor fuel economy, factory settings often hold your truck back. Our upgrades deliver:

  • More usable torque

  • Improved throttle response

  • Better fuel efficiency

  • Enhanced towing performance

  • Safer overtaking and hill climbs

We fine-tune your Chevy to meet real-world Aussie conditions – without compromising safety, drivability or reliability.

What We Upgrade – Chevy Truck Performance Services

We don’t believe in one-size-fits-all. Every Chevy truck gets a tailored performance package based on how you drive and what you use it for. Common models we work on include:

  • Chevy Silverado 1500
  • Chevy Silverado 2500HD
  • Chevy 3500 & Heavy-Duty Pickups
  • Chevy Express Diesel (work vans)

ECU Remapping (Custom Tunes)

Our ECU remapping adjusts your Chevy’s engine management system to deliver more torque, quicker throttle, and cleaner fuel delivery.

✅ Designed to work with Aussie fuel
✅ Tailored for towing, long hauls, or off-road
✅ Safe for engine longevity and emissions systems
✅ Fully reversible if needed

Carbon Cleaning & Diagnostics

Chevy trucks that idle a lot or do short trips often suffer from carbon build-up. Our carbon cleaning service restores airflow and power while reducing emissions.

✅ Boosts engine responsiveness
✅ Improves fuel economy
✅ Prevents long-term damage

Exhaust & Intake Upgrades

Factory intake and exhaust systems are often restrictive. We upgrade both for better airflow, improved turbo response, and more efficient combustion.

✅ Performance stainless exhausts
✅ High-flow air intake systems
✅ Optional intercooler upgrades

Suspension & Towing Mods

Need better stability under load or off-road? We can upgrade your suspension to improve ride quality, load handling and safety.

✅ Leaf spring, airbag, and shock upgrades
✅ Ideal for caravans, boats or work trailers

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.
