Popular Engine Modifications

Among the most popular modifications is the installation of a turbocharger or supercharger. These devices force more air into the engine, allowing for more fuel combustion and increased power. Turbocharging is often preferred for its efficiency in boosting power without compromising fuel economy, while supercharging is known for providing an immediate increase in horsepower.

Another common modification is ECU remapping. This process involves altering the software that controls engine functions to optimize performance. ECU remapping can improve throttle response, increase horsepower, and enhance fuel efficiency. It's essential, however, to have this done by professionals to avoid potential damage to the engine.
