ECU Remapping & Dyno Tuning

Dyno Tuning for Diesel Vehicles

ECU Remapping is the best and most cost-effective way to improve your vehicle’s performance for when and where you need it most. Core Diesel Custom Diesel Tuning can enhance driveability, throttle response, off-road performance, towing ability, and efficiency, ultimately increasing fuel economy while unlocking your vehicle’s full potential.
We only use the best when it comes to modifying any vehicle. We have a purpose-built soundproof Dyno cell with the latest technology, Mainline Chassis Dyno, capable of up to 850KW ( 1130hp) and 1700nm ( 1254 Ftlb ) of torque.
This gives us the ability to ensure that you receive the best possible performance result, safely & reliably. We provide a “Before and After Dyno sheet” to show your power and torque gains achieved.
We offer a variety of packages and options to help you safely achieve the goals you have in mind for your vehicle. Whether it’s towing, touring, fuel economy, or even all-out power, we have got you covered! Contact our team today to discuss creating a custom package tailored to your specific needs.
Benefits of Performance Tuning
What Sets Core Diesel Apart?
At Core Diesel, we don’t believe in one-size-fits-all solutions – because no one tune suits all. Unlike generic “car park tunes” or plug-and-play chips, our remaps are fully customised to your engine, vehicle setup, and specific use case.
We use industry-leading tuning software and advanced diagnostic tools to deliver reliable, road-tested results. Every tune is backed by real data from our dyno runs and performed by experienced diesel tuning technicians who understand what your vehicle needs.
We’re proud to be the only diesel tuning shop on the Fraser Coast offering dyno tuning and real-data-backed performance tuning tailored specifically to your vehicle. That’s the Core Diesel difference.

This is the most common package we do for people that like to get away with the van on the back & explore the open & off-road adventures.
