Mercedes E63 AMG W212 Tuning Guide
E63 AMG W212 Tuning Guide
The Mercedes-Benz E63 AMG W212, produced between 2009 and 2016, is a powerful and high-performance vehicle. Whether you are looking to enhance its performance, improve handling, or add a unique touch to its appearance, tuning an E63 AMG W212 can significantly alter the driving experience. However, before diving into any modifications, it’s important to understand the differences between the M156 and M157 engines, what hardware is required for tuning, and the impact that modifications may have on the vehicle’s overall upkeep.
Engine Differences: M156 vs. M157
The E63 AMG W212 was offered with two different engines during its production run: the M156 and the M157.
- M156 Engine (2009-2011): The earlier models of the E63 AMG W212 feature the naturally aspirated 6.2-litre V8 M156 engine. This engine produces around 518 horsepower and 630 Nm of torque. While the M156 offers a raw, naturally aspirated engine note, its performance ceiling is slightly lower than that of the M157 engine.
- M157 Engine (2012-2016): From 2012 onwards, Mercedes-Benz switched to the turbocharged 5.5-litre V8 M157 engine. This engine delivers significantly more power, ranging from 518 to 577 horsepower, depending on the specific model and tuning. The M157 engine is more efficient and offers more tunability, with its forced induction providing a greater scope for power gains.
Understanding these differences is important when tuning the E63 AMG W212, as the M157 engine offers more potential for power increases through tuning due to the turbochargers.
Performance Tuning
ECU Remapping/Chip Tuning
One of the first tuning modifications for both the M156 and M157 engines is ECU remapping (or chip tuning). By adjusting the software settings in the engine control unit, you can increase power, improve throttle response, and optimise fuel efficiency. For the M157, a remap can result in a significant power increase, particularly for the higher-output variants, pushing the vehicle's performance closer to 650 horsepower or beyond. On the M156, a remap can improve performance, but the gains are typically lower when compared to the turbocharged M157.
Exhaust System
Upgrading the exhaust system can unlock additional power and improve sound. A high-flow, performance exhaust will reduce backpressure and allow the engine to breathe more easily, providing slight increases in power and torque. For the M156 engine, an upgraded exhaust system can enhance the engine's natural sound, while for the M157, it can complement the turbocharged nature of the engine.
Forced Induction
For owners of the M157 engine, additional gains can be achieved through upgrades to the turbochargers. Larger or more efficient turbochargers can provide increased boost pressure, leading to significant power gains. However, it’s important to ensure that the engine internals and fuel system are upgraded to support the added power, including stronger pistons, connecting rods, and a high-flow fuel pump. The M156, being naturally aspirated, cannot benefit from turbo upgrades but can see improvements through intake and exhaust modifications.
Air Intake System
Upgrading the air intake system is another common modification for improving engine performance. Aftermarket cold air intakes and high-flow filters can increase airflow to the engine, improving performance at higher revs. While the M157 benefits more from a larger intake due to its forced induction setup, the M156 can also benefit from a performance intake, particularly when combined with other upgrades.

Suspension and Handling
For those looking to improve handling and cornering performance, suspension modifications are key. The E63 AMG W212 comes with a sports suspension as standard, but owners looking for more aggressive handling characteristics may opt for lowering springs or coilovers to lower the car's stance and reduce body roll.
Upgraded sway bars and strut braces can also improve stability during high-speed cornering. Additionally, performance shocks and springs will help improve the ride quality and handling balance.

Braking System
The E63 AMG is already equipped with powerful braking components, but any performance upgrade will put additional strain on the braking system. To cope with the increased power and potential higher speeds, upgrading to larger carbon-ceramic brakes or high-performance aftermarket discs and pads is advisable. The E63’s brakes may wear more quickly after performance modifications, so regular inspection and servicing are important to avoid brake fade and maintain stopping power.

Cooling System
With performance upgrades, particularly in the form of increased power from the engine, additional cooling may be required. A larger or more efficient intercooler for the M157 engine can help maintain lower intake temperatures, preventing heat soak and ensuring consistent performance. For the M156, upgrading the radiator or adding an oil cooler may be beneficial in maintaining optimal engine temperatures during extended periods of spirited driving.
Transmission and Drivetrain
When tuning the E63 AMG W212, the transmission should also be considered. The 7-speed AMG SPEEDSHIFT MCT gearbox can handle the power output of the M156 and M157 engines, but performance modifications may require software tuning to optimise shift points, especially if you have increased power significantly. If the drivetrain is modified, consider upgrading the clutch packs or other components of the transmission to ensure longevity and reliability.
Impact on Consumables and Servicing
Tuning the E63 AMG W212 can have a notable impact on the vehicle’s consumables, such as tyres, brake pads, and engine oil. With increased power, the vehicle will place greater demands on the tyres, which may wear out more quickly, especially if driven aggressively. Upgraded brake pads and rotors will also be needed more frequently, as increased performance will result in higher braking temperatures and wear.
Oil changes will become more critical, especially when pushing the engine’s performance limits. Higher-performance engines, particularly with added power from forced induction or remaps, may require more frequent oil changes to maintain lubrication under higher stress.
Considerations Before Modifying
Before starting any tuning project, there are several important factors to consider:
- Warranty: Any modifications will likely void the manufacturer’s warranty, so it’s important to weigh the risks before modifying the vehicle.
- Legal Considerations: Some modifications, particularly to the exhaust or emissions systems, may not comply with local regulations. Ensure that any modifications are legal for road use in your area.
- Insurance: Modifying your vehicle will often increase your insurance premiums. Be sure to inform your insurer of any changes to avoid complications in the event of a claim.
- Costs: High-performance parts and tuning services can be expensive, and the long-term cost of maintaining a modified vehicle can increase, especially in terms of regular servicing and repairs.
Conclusion
Tuning an E63 AMG W212 can provide a significant boost in performance and driving enjoyment, but it’s essential to approach modifications carefully. Whether you have the M156 or M157 engine, the right combination of ECU remapping, exhaust upgrades, suspension modifications, and cooling system improvements can make a noticeable difference. However, it’s important to be aware of the impact on consumables, servicing, and the overall cost of ownership when modifying this high-performance vehicle. By choosing reliable components and ensuring regular maintenance, you can enjoy the benefits of a tuned E63 AMG W212 while maintaining its reliability and performance.
