MERCEDES-AMG C63S M177
Mercedes-AMG C63S W205 Tuning & Performance Upgrades
4.0L Twin-Turbo V8 (M177) | AMG Speedshift MCT | Australia
The Mercedes‑AMG C63 S (2021–2024) represents one of the final and most sought-after V8 AMGs ever produced. Powered by the 4.0-litre M177 twin-turbo V8 and paired with the AMG Speedshift MCT transmission, the C63S delivers raw performance, unmistakable sound, and serious tuning potential.
From the factory, however, the C63S is deliberately torque-managed and emissions-restricted, leaving significant performance on the table — especially in throttle response, mid-range torque, and gearbox behaviour.
At Diesel & Performance Tuning Brisbane, we offer custom ECU and TCU calibration for the C63S W205, developed for Australian conditions, fuel quality, and real-world drivability.

Package Upgrades
Information about the upgrades included and available options for your vehicle.
ECU Remap
Our C63S AMG ECU calibration is a fully custom engine remap developed specifically for the M177 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 C63S 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 C63S 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 C63S AMG.
Includes:
- 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 C63S 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
CPC Remap
Our C63S AMG CPC calibration is a critical upgrade that is required for Stage 3 and Stage 3+ packages to complement the ECU and TCU remap by optimising the Central Powertrain Controler logic to handle increased torque safely and efficiently, without inhibitions of torque, and speed limitaitons. The CPC also controls systems such as the exhaust flap control logic, drive-mode select and 4-Matic drive systems, and other various functions such as left-foot braking, launch control, and other key features can be optimised to break the 1000Nm/600kW barrier, espeically when implementing turbocharger and fuel systems upgrades.
Includes:
- Preliminary Health Inspection
- Full System Diagnostic Scan
- Prelimary Test Drive
- Prelimiary Data Logging
- CPC Calibration
- Calibrated Data Logging
- Final Test Drive
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

About the Mercedes-AMG C63S (M177)
Key platform highlights:
-
4.0L M177 twin-turbo V8
-
AMG Speedshift MCT (wet clutch)
-
Rear-wheel drive
-
Factory output ~375kW / 700Nm
-
Active engine mounts and performance exhaust (model-dependent)
While the hardware is extremely capable, factory calibration prioritises global emissions compliance, traction management, and drivetrain protection, especially in lower gears.
Mercedes-AMG C63S ECU Remapping & Dyno Tuning
Our C63S ECU calibration focuses on usable, repeatable performance, not inflated dyno numbers.
ECU tuning benefits:
-
