What is the most efficient way to increase horsepower in a BMW M4?

I have a BMW M4 and I want to optimize its performance. What is the best way to increase horsepower without sacrificing reliability?

There are various ways to increase horsepower in a BMW M4, such as installing a high-flow air intake and exhaust system, upgrading the engine control unit, or adding a turbocharger. However, it's important to choose a reputable and experienced mechanic to ensure proper installation and avoid any potential issues down the road.

Another option is to upgrade the internal engine components, such as the pistons, connecting rods, and crankshaft. This can significantly increase horsepower, but it's a more expensive and complex process. It's important to do your research and consult with a professional before making any modifications to your engine.
