Fuel prices in South Africa are Rising and Changing Driving Priorities Fuel prices in South Africa have seen significant increases, placing added pressure on daily drivers, fleet operators, and businesses that rely on vehicles for transport. For many vehicle owners,...
Overlanding and Touring: How to Tune for Reliability, Not Stress
What Is an Overlanding Truck Setup? An overlanding truck setup is a vehicle configured for long-distance, off-road travel, typically equipped with additional load such as rooftop tents, recovery gear, and storage systems. This added weight and sustained operating...
Why “More Boost” Isn’t Always More Power
Introduction: The Boost Myth in Performance Tuning Boost pressure is often treated as a shortcut to power. The assumption is simple: increase boost and power will follow. In practice, this mindset leads to inefficient tuning and, in some cases, mechanical failure....
Before & After: What a Proper Diesel Tune Actually Changes
Power Gains Are Only Part of the Story Diesel tuning is often judged by a single metric: peak power. This narrow focus creates unrealistic expectations and, in many cases, unsafe tuning outcomes. A proper diesel tune does not simply add fuel and boost. It refines how...
Dyno Health Checks: When Performance Testing Saves Engines
Performance Testing Is Not Just About Power Dynamometer testing is often associated with increasing power output. While performance gains are a valid outcome, this narrow view overlooks one of the dyno’s most valuable roles: engine health assessment. For vehicles that...
