A tuned car is a standard production vehicle that has been modified to enhance its performance, handling, or aesthetics beyond its factory specifications. This process, known as car tuning, involves making aftermarket changes to components like the engine, suspension, exhaust, and bodywork. The primary goal is to personalize the car to the owner's specific preferences, whether for faster acceleration, sharper cornering, or a more aggressive appearance. Tuning can range from simple, affordable modifications to extensive, professional builds. Common modifications include: * **Engine Tuning (ECU Remap):** The most significant upgrade is often remapping the **Engine Control Unit (ECU)**, the car's central computer. By adjusting parameters like fuel injection and turbocharger boost pressure, tuners can extract more horsepower and torque from the engine. * **Exhaust Systems:** Upgrading to a performance exhaust reduces backpressure, which can improve engine efficiency and produce a more powerful sound. * **Suspension:** Lowering springs or coilover kits lower the car's center of gravity, reducing body roll and improving handling. Upgraded sway bars further enhance cornering stability. * **Wheels and Tires:** Lighter alloy wheels and high-performance tires provide better grip and braking, directly translating the increased power to the road. It's crucial to understand that tuning can affect your vehicle's warranty and insurance. Major modifications should be performed by reputable professionals to ensure reliability and safety. The table below shows potential power gains from common engine tuning levels on a turbocharged four-cylinder engine. | Tuning Stage | Typical Modifications | Estimated Power Gain | Key Consideration | | :--- | :--- | :--- | :--- | | **Stage 1** | ECU Software Remap | +15% to +30% | Minimal hardware changes; often warranty-friendly from some tuners. | | **Stage 2** | ECU Remap + Performance Exhaust + High-Flow Air Filter | +30% to +50% | Requires supporting hardware; may need upgraded clutch. | | **Stage 3** | Larger Turbocharger, Upgraded Fuel System, Internal Engine Work | +50% to +100%+ | Significant investment; requires professional installation and tuning. |

Tuning Stage	Typical Modifications	Estimated Power Gain	Key Consideration
Stage 1	ECU Software Remap	+15% to +30%	Minimal hardware changes; often warranty-friendly from some tuners.
Stage 2	ECU Remap + Performance Exhaust + High-Flow Air Filter	+30% to +50%	Requires supporting hardware; may need upgraded clutch.
Stage 3	Larger Turbocharger, Upgraded Fuel System, Internal Engine Work	+50% to +100%+	Significant investment; requires professional installation and tuning.
