MERCEDES-AMG S63 M157
Mercedes‑AMG S63 ECU Remap & Performance Tuning
At Diesel & Performance Tuning Brisbane, our tuning for the W222 Mercedes-AMG S63 (M157 5.5L Twin-Turbo V8) is focused on real-world performance, drivability, and long-term reliability — not inflated dyno numbers or aggressive flash files.
The M157 is an exceptionally strong AMG engine that is heavily detuned from factory. With correct ECU and TCU calibration, it delivers effortless torque, sharper response, and a driving experience that finally matches the S63 badge — while retaining the refinement expected of an S-Class.

ECU Remap
Our S63 AMG ECU calibration is a fully custom engine remap developed specifically for the M157 5.5L Bi-Turbo V8 platform. Unlike generic flash files, our ECU tune recalibrates boost pressure control, torque modelling, ignition timing, fuel delivery of both high and low pressure systems, and throttle mapping to safely unlock performance the factory calibration leaves on the table. The result is stronger mid-range torque, sharper throttle response, and smoother power delivery across the rev range, while retaining OEM-level drivability and reliability. This S63 AMG ECU remap is ideal for both stock vehicles and those fitted with performance upgrades such as intakes, downpipes, or exhaust systems.
Includes:
- Preliminary Health Inspection
- Full System Diagnostic Scan
- Prelimary Test Drive
- Prelimary Dyno Testing
- Prelimiary Data Logging
- ECU Calibration
- Calibrated Dyno Testing
- Calibrated Data Logging
- Final Dyno Test & Report
- Final Test Drive
TCU Remap
Our S63 AMG TCU calibration is a critical upgrade that complements the ECU remap by optimising the 9 speed transmission logic to handle increased torque safely and efficiently. This transmission tune improves shift speed, optimises torque reduction during gear changes, increases clamping pressure on the clutch packs, and refines shift behaviour in all drive modes from Comfort through to Sport and Sport+ modes. The result is faster, firmer, and more consistent gear changes, improved launch performance, and a far more connected driving experience. Without a TCU remap, the factory transmission strategy can limit the full potential of an ECU-tuned S63 AMG.

- Preliminary Health Inspection
- Full System Diagnostic Scan
- Prelimary Test Drive
- Prelimiary Data Logging
- TCU Calibration
- Calibrated Data Logging
- Final Test Drive
Exhaust Upgrade
An exhuast upgrade, whether cat-back, downpipe, or even a coplete exhaust upgrade for the S63 enhances both performance and sound by improving exhaust flow downstream of the turbochargers. Designed to reduce restriction while maintaining proper exhaust velocity, a quality exhaust system delivers a deeper, more aggressive exhaust note without excessive drone. While power gains are modest on their own, an exhaust complements ECU tuning and downpipe upgrades perfectly, completing the system for improved sound, efficiency, and overall driving experience.
Includes:
- Cat-back Exhaust Upgrade OR Full Exhaust Upgrade OR Downpipes (please contact to discuss).
- Gaskets & V-Band Clamps
- Installation
Turbocharger Upgrade
Orignal BorgWarner turbochargers with TTE760 9 Blade turbines paired with the 7x7 compressor is a special turbine designed by TTE. Advantages are greater gas flow, reducing backpressure, and lowering exhaust gas temperatures, allowing safer, yet higher boost levels. This turbine material, and wheel itself is extremely light in mass, thus provides a reduced effort required for inertia, meaning faster spool up for the size. Capable of 600kW on 98 Octane Pump Fuel!
Includes:
- All consumables for installation
- Original (Brand New) Modified BorgWarner turbochargers
- 7+7 TTE Billet Compressors 56mm Inlet
- 9 Blade TTE Turbines 54mm Outlet
- Plug and Play installation
- 600+kW on 98ron
- Single parts finely balanced then components assembled and core high-speed VSR balanced
- Supplied with a balance test result document
- 12 Month Component Warranty
- Made in Germany
HPFP Upgrade
Required for Stage 3+ package to support increased boost level. The OEM HPFP is not capable of supporting sufficient fuel delivery for up to 40psi. High pressure fuel pump upgrade is a must-have, non-negotiable compoenent to ensure engien safety for high power tuning packages.
Includes:
- HPFP
- Installation
- 12 Month Component Warranty
- Made in USA

More Vehicle Details
Our ECU Remap – M157 5.5L Twin-Turbo
Our custom ECU remap for the W222 S63 is developed in-house and tailored to the vehicle, fuel quality, and usage. We do not use generic or overseas files.
What our S63 ECU remap delivers:
-
Strong gains in power and torque, particularly mid-range
-
Noticeably sharper throttle response
-
Improved boost control and torque modelling
-
Smoother power delivery under part-throttle
-
Retention of all factory safety strategies
The result is an S63 that feels lighter, more responsive, and far more engaging, without compromising comfort or reliability.
TCU Remap – AMG SPEEDSHIFT MCT
The factory gearbox calibration prioritises smoothness and driveline protection, which can feel lazy once additional torque is unlocked. Our TCU remap is designed to complement the ECU calibration.
TCU tuning benefits:
-
Faster, cleaner gear shifts
-
Improved torque handling logic
-
Reduced shift hesitation
-
Better response in Sport and Manual modes
-
Improved overall drivability
Exhaust Upgrades (Optional)
The M157 V8 is known for its deep, aggressive AMG sound, much of which is muted from factory. We offer select exhaust upgrade solutions that restore character without drone or harshness.
Our focus:
-
Quality cat-back systems
-
Valve-controlled options where applicable
-
Improved flow to support tuning
-
Refined AMG tone — not excessive noise
Exhaust upgrades pair exceptionally well with our ECU remap but are not mandatory for excellent results.

Frequently Asked Questions – W222 S63 AMG
Will tuning affect reliability?
No — our tuning is designed to operate within safe mechanical limits. We avoid aggressive boost or unsafe ignition strategies.
Does tuning affect warranty?
ECU and TCU tuning may impact the manufacturer's warranty. We provide our own extended warranty, and we’re happy to disclose options and expectations before proceeding.
What fuel is required?
98 RON premium fuel is required for all tuned M157 vehicles.
Is this suitable for daily driving?
Yes. Our S63 tunes prioritise smoothness and drivability as much as outright performance.
