Frequently Asked Questions
Are performance modifications legal in Queensland?
Many performance modifications are legal in Queensland, but they must comply with the Department of Transport and Main Roads regulations.
Some upgrades require engineering certification or a modification plate to be legally driven on public roads. Always check the guidelines or speak with an approved certifier before starting any major vehicle modifications.
Do performance modifications affect fuel economy?
Yes, performance modifications can affect fuel economy—positively or negatively. Some upgrades, like ECU tuning or intake systems, may improve efficiency under certain conditions.
However, mods that increase power output often lead to higher fuel consumption, especially if you drive more aggressively. It's all about balance between performance gains and how you use your vehicle day to day.
What are the best performance modifications to increase horsepower?
Some of the most effective performance modifications for boosting horsepower include ECU remapping, turbo or supercharger installations, upgraded exhaust systems and cold air intakes.
These upgrades improve airflow, fuel delivery and engine efficiency. The best combination will depend on your car’s engine, current setup and goals, so it’s important to choose compatible modifications for optimal results.
