AMG GT C190 Tuning Guide: Enhancing Your Supercar

The Mercedes-AMG GT C190, first introduced in 2016, is a highly refined and performance-focused supercar that many owners prefer to keep in its factory configuration. However, there are enthusiasts who want to enhance the driving experience further, whether through performance improvements, sound modifications, or aesthetic upgrades. This guide provides an overview of the types of tuning and modifications you can make to your AMG GT C190 to elevate its performance, sound, and appearance.

Performance Enhancements
While the AMG GT C190 comes with a formidable 4.0-litre twin-turbocharged V8 engine, there are several tuning options to further increase its performance without altering the fundamental character of the car.
Exhaust Systems
One of the most popular modifications for the AMG GT is upgrading the exhaust system. Not only does a new exhaust system improve sound, but it can also help reduce weight and improve exhaust flow, potentially leading to a slight increase in horsepower. Popular brands like Akrapovič, Milltek, and Remus offer exhaust systems designed specifically for the AMG GT, each giving the car a more aggressive and distinctive exhaust note.
Downpipes: Replacing the factory downpipes with less restrictive, high-performance alternatives can help improve turbo efficiency, reducing turbo lag and increasing power output. This modification is particularly useful if you're aiming for better performance without a full engine rebuild.
Intake and Cooling Systems: Upgrading the intake system can help increase airflow into the engine, improving combustion efficiency. A high-flow air intake filter can allow the engine to breathe better, potentially adding a few horsepower.
Additionally, upgrading the intercoolers and cooling system can help lower intake air temperatures, which improves the overall efficiency of the turbochargers, particularly in hotter conditions or during high-performance driving. These modifications can help maintain consistent power delivery, especially for track-focused applications. Check out the cooling items available for your AMG GT here.
ECU Tuning: ECU tuning or remapping is one of the most effective ways to increase engine power without the need for physical hardware changes. By modifying the software that controls the engine’s parameters, such as fuel maps, boost pressure, and timing, a custom ECU tune can optimise the performance for more power, quicker throttle response, and improved fuel efficiency. It’s essential to ensure the tune is done by a professional familiar with the AMG GT’s electronics to avoid any potential engine issues.
Suspension and Handling
If you’re looking for improved handling, particularly for track use, upgrading the suspension system can make a significant difference. Coilover kits, adjustable dampers, or upgrading to a more performance-oriented suspension can improve cornering ability and responsiveness.
Upgraded Anti-Roll Bars: Fitting thicker anti-roll bars helps reduce body roll, improving stability in high-speed corners, which can significantly enhance the driving experience.
Lowering Springs: For those who want a sportier look and improved handling dynamics, lowering springs are a common modification. They lower the centre of gravity and improve handling but can stiffen the ride, so it’s important to balance ride comfort with performance. Check out AMG GT Suspension products here!
Aesthetic Modifications
While the AMG GT C190 has a striking and aggressive design right from the factory, some owners may choose to further personalise its appearance. Aesthetic modifications can enhance the car’s visual appeal and give it a more distinctive, individual look.

Body Kits and Aero Enhancements
A body kit is a popular choice for those looking to give their AMG GT a more aggressive stance. These kits typically include front and rear bumpers, side skirts, and sometimes a rear diffuser or a front splitter. These parts are often made from lightweight materials like carbon fibre, which not only improve the car's aesthetics but also reduce weight.
Carbon Fibre Components: Adding carbon fibre accents to the mirrors, bonnet, and rear wing is another popular choice. The lightweight material adds a motorsport-inspired look while also offering performance benefits due to its reduced weight.
Rear Spoilers and Diffusers: A rear spoiler or diffuser can improve the car’s aerodynamics, especially at higher speeds. These parts can help to increase downforce and improve stability, particularly for those using their car on track.
Wheels and Tyres
Upgrading the wheels can dramatically change the look of your AMG GT. Lightweight forged wheels, such as those from brands like HRE or BBS, reduce unsprung weight, which can improve handling and braking performance. Larger wheels with a more aggressive offset are also an option if you want to further personalise the car’s appearance.
Pairing new wheels with high-performance tyres designed for better grip can also improve the driving experience, particularly in wet or dry conditions.
Conclusion
The AMG GT C190 is already an exceptional vehicle, but for those looking to enhance their car further, there are plenty of tuning options available. Whether it’s boosting performance with a new exhaust system or improving handling with suspension upgrades, the key is to balance performance gains with maintaining the car’s core qualities.
When considering any modification, it’s crucial to ensure that the changes are made with careful attention to the car’s overall performance and reliability. Whether you want to increase power, improve the driving experience, or give your AMG GT a personalised look, tuning it to your preferences can elevate the ownership experience.
Always ensure that any modifications are done by professionals familiar with the AMG GT, as improper tuning can lead to long-term issues or void warranties.
