The BMW F90 M5 is already a powerhouse straight from the factory, but for those who crave even more power and performance, modifications are the key. With its twin-turbocharged V8 engine and advanced technology, the F90 M5 provides an excellent platform for power-boosting enhancements. In this guide, we'll dive into the world of performance modifications to help you unlock the full potential of your F90 M5.

1. ECU Remapping

One of the most effective ways to extract more power from your F90 M5's engine is through an ECU remap (Engine Control Unit). This involves reprogramming the car's onboard computer to optimize various parameters such as fuel delivery, ignition timing, and boost pressure. Reputable tuning companies like ECM Tuner, AC Schnitzer, and ESS Tuning offer ECU remaps that can deliver substantial gains in horsepower and torque.

2. Exhaust Upgrades

Enhancing the exhaust system can significantly contribute to increased power and a more aggressive sound. Aftermarket exhaust systems with larger diameter pipes, high-flow catalytic converters, and less restrictive mufflers can reduce backpressure and improve exhaust flow. Brands like Akrapovič, Eisenmann, and Remus offer exhaust systems that not only add power but also enhance the auditory experience.

3. Intake System Improvements

Upgrading the intake system can help the engine breathe more freely and deliver more air to the combustion chambers. High-flow air filters and cold air intake kits can improve airflow, leading to better throttle response and increased power output. Look for quality components from manufacturers like BMC Air Filters, Velocity Intakes and Eventuri.

4. Turbocharger Upgrades

For those seeking substantial power gains, turbocharger upgrades are a serious option. Upgraded turbochargers can provide higher boost levels and increased airflow, resulting in significant horsepower and torque increases. However, turbocharger upgrades on F90 require more extensive modifications to the engine ( forged internals) and tuning adjustments to ensure proper functionality and reliability.

5. Performance Downpipes

Replacing the stock catalytic converters with performance downpipes can further reduce exhaust backpressure and improve exhaust gas flow. This modification is typically combined with an ECU remap to fully capitalize on the increased flow. Be aware that changing the catalytic converters might affect emissions compliance and legality in some regions.

6. Intercooler Upgrades

Intercoolers play a crucial role in cooling the air compressed by the turbochargers before it enters the engine. Upgrading to larger and more efficient intercoolers can help maintain lower intake air temperatures, allowing for more consistent power output. Brands like Wagner Tuning and Eventuri offer intercooler upgrades specifically designed for the F90 M5.

7. Fuel System Enhancements

As you push your F90 M5's engine to higher power levels, the fuel system might need an upgrade to ensure proper fuel delivery. Upgraded fuel pumps, injectors, and lines can provide the necessary flow for increased horsepower and prevent fuel delivery issues under high load conditions.

Safety and Reliability

While chasing more power is exhilarating, it's essential to approach these modifications with caution. Pushing an engine beyond its limits can result in reliability issues or even catastrophic failure. Always work with reputable tuning shops, follow manufacturer guidelines, and prioritize proper maintenance to keep your F90 M5 running smoothly.

In conclusion, unlocking more power from your BMW F90 M5 is an exciting journey that requires careful planning and execution. By combining ECU remapping, exhaust upgrades, and other performance enhancements, you can transform your already impressive M5 into a true powerhouse on the road. Just remember to balance power gains with reliability and safety for a thrilling driving experience that you can enjoy for years to come.
