MERCEDES-AMG GT 53 4MATIC+ 4-DOOR COUPÉ - X290 (2018 to Present) STAGE 1 & STAGE 2 PERFORMANCE TUNE
The Mercedes-AMG GT 53 4MATIC+ 4-Door Coupé blends luxury, performance, and everyday usability in a way few vehicles can. Powered by the AMG enhanced 3.0L inline 6 turbo engine with mild hybrid assist, the GT 53 already delivers strong factory performance, but the platform has considerably more to offer through proper ECU calibration.
Our AMT performance tuning sharpens throttle response, increases torque throughout the rev range, and gives the GT 53 a much stronger and more urgent character, especially in the mid range where the car feels noticeably more alive. The result is a faster, sharper, and more responsive driving experience while maintaining the refinement expected from an AMG grand touring platform.
• Sharper throttle response
• Stronger mid range acceleration
• Improved top end pull
• More aggressive and responsive power delivery
• Optimized drivability and engine response
• Premium fuel calibration
• Individual ECU reprogramming
• Original factory file stored for return to stock where applicable
• Stage 1 Tune
• Stage 2 Tune
Also known as Crackle Map, Burble on Overrun, or Schubblubbern, this feature adds a sharper exhaust crackle sound when lifting off the throttle.
This option is designed to give the vehicle a more aggressive exhaust character during deceleration and overrun, while also helping maintain a more responsive feel when getting back on the throttle. It is a popular option for customers looking for a more race inspired sound and a more dramatic driving experience.
This option disables the factory automatic start and stop function, so the engine will no longer automatically shut off when the vehicle comes to a stop.
It is a popular feature for customers who prefer a more consistent driving experience without repeated engine shut off and restart during normal driving.
Exhaust Flap Control allows the calibration of the factory exhaust valve behavior for a more aggressive exhaust sound when desired.
When the valves are closed, the exhaust remains quieter and more restrained. When opened, the exhaust system operates in a higher flow and louder sound mode, giving the vehicle a more pronounced AMG exhaust character.
The factory catalyst heating strategy is designed to bring the catalytic converters up to operating temperature as quickly as possible after cold start. This is typically achieved by raising idle speed and adjusting ignition timing during the initial startup phase.
Disabling this function can reduce the louder cold start behavior that many customers find excessive, especially on vehicles equipped with less restrictive exhaust hardware or catless setups.
| Specification | Original | Stage 1 | Stage 2 |
|---|---|---|---|
| Power (HP) | 429 | 490 | 510 |
| Torque (lb.ft) | 384 | 457 | 472 |
Stage 1
Stock vehicle or lightly modified vehicle
High quality panel filters recommended
Stage 2
Freer flowing intake and exhaust hardware recommended
Production Date: 2018 to Present
Engine: 3.0L Inline 6 Turbo
Drivetrain: 4MATIC+
Transmission: Automatic
Programming Method: BENCH
ECU Programming Method: BENCH
Reading and programming are carried out directly through the control unit connector on the bench.
This means the ECU must be removed from the vehicle and programmed directly on the bench.
If you are unable to bring the vehicle to us, the ECU can be removed and shipped to AMT Tuning for bench programming.
Please make sure the ECU is packed securely and that the package includes a note with the following information:
• Full name
• Order number
• VIN number
• Vehicle year and model
• Contact email
• Contact phone number
This information is required so we can correctly identify the ECU and match it to your order before programming begins.
Please pack the ECU securely using anti static material and/or bubble wrap.
Ship in a strong padded box with tracking and insurance.
Improper packaging may result in damage during transit.

❓ Frequently Asked Questions🔧 What Is Chiptuning and How Does It Work?
Every modern engine with electronic fuel injection is controlled by an Engine Control Unit (ECU) — a computer that manages ignition timing, fuel injection, throttle mapping, and other vital parameters.
Chiptuning is the process of reprogramming that ECU with optimized calibration data. By adjusting the software that governs how the engine operates, we can safely improve power output, torque delivery, throttle response, and even fuel economy — all without adding physical modifications.
At AMT Tuning, each tune is based on in-house data-logging and dyno testing to ensure the perfect balance between performance, reliability, and efficiency.
⚡ What Are the Benefits of Chiptuning?
Chiptuning delivers noticeable improvements in both performance and everyday drivability. Key benefits include:
🚗 Increased horsepower and torque for faster acceleration
🏎️ Sharper throttle response and reduced delay between pedal and power
🔄 Smoother torque curve and safer overtaking ability
💨 Improved fuel efficiency under normal driving conditions
🔋 Custom options such as Pops & Bangs, launch control, and limiter adjustments
Each calibration is developed to enhance your car’s personality while maintaining factory-level reliability.
🛡️ Is Chiptuning Safe for My Engine?
Absolutely. Our Stage 1 remaps and all standard performance tunes are designed well within OEM safety margins for air-fuel ratio, ignition timing, exhaust gas temperature, and torque limits.
We never disable critical engine protection functions. Instead, AMT Tuning recalibrates these systems to operate more efficiently, giving you stronger performance without sacrificing durability.
✔️ 100 % safe for daily driving✔️ Does not reduce engine lifespan✔️ Fully reversible to stock at any time
📱 How Is the Tune Installed?
All AMT Tuning packages use the Powergate 4 OBD flashing tool with smartphone integration.
No PC or laptop required
Works via Bluetooth and Wi-Fi
Read your ECU, upload the file, and flash your tuned map directly from the app
Revert to stock whenever you wish
Setup takes only a few minutes, and support is available directly through the app or our email team.
🧰 Do I Need Other Parts Before Tuning?
For Stage 1, no modifications are required — though we recommend a K&N drop-in filter for best results.For higher stages (Stage 2 and above), supporting parts such as cold air intake, cat-back exhaust, or 2J Racing headers are recommended to maximize performance potential.
Each product page on our website lists the exact hardware requirements for every stage.
