Calibration Details
In-House Powertrain Calibration
With Stage 1 software, gains reach up to 100 HP / 101 PS plus 125 lb-ft / 169 Nm; the resulting figures are approximately 529 HP / 536 PS and 538 lb-ft / 729 Nm.
The Stage 2 calibration delivers up to 120 HP / 122 PS and 143 lb-ft / 194 Nm above stock, moving output to about 549 HP / 557 PS and 556 lb-ft / 754 Nm.
ECU Unlock
An ECU unlock is the process of removing the manufacturer's read/write protection on a vehicle's engine control unit, giving tuners access to the internal calibration data using flash tools. This restores the ability to read the original calibration, modify maps and parameters, and write custom software back to the unit, forming the foundation that other services, like map switching or custom calibration, are built on top of.
CPC Calibration
Our AMG CPC Calibration Upgrade optimizes torque monitoring to support increased engine output and reduce unnecessary torque intervention.
It maintains coordinated communication between powertrain controllers for more consistent performance under high loads.
9G TCU Calibration
Our AMG TCU Calibration Upgrade delivers faster gear changes, more responsive downshifts, and improved gear holding during acceleration.
Optimized to complement our ECU calibration, it improves power delivery while maintaining smooth everyday drivability.
