About South West Tuning Co.
Based in WA’s South West, we provide mobile tuning with the convenience of on-site service. We deliver safe, reliable engine and transmission remapping for passenger vehicles, 4WDs, and offer a range of performance and reliability solutions for Trucks, Civil & Ag equipment.
Importance of Regular Maintenance
While remapping unlocks performance and efficiency, regular vehicle maintenance is essential for long-term reliability. Keeping up with scheduled servicing — oil and filter changes, fluids, cooling system checks, and inspections — helps your engine and transmission make the most of the tune and prevents premature wear.
We recommend 10,000km or yearly service intervals (at minimum) and addressing any warning lights promptly. A well-maintained vehicle not only performs better but also keeps your investment safe and dependable.
We use and recommend
lubricants and fluids to maintain optimum performance and durability in Australian conditions.
