Performance Expectations (Stage 1)
Mercedes significantly underrates the M177 EQ-Boost platform. With AMR calibration, customers commonly experience:
Stage 1: +90–100 HP
Stage 1: +120–130 LB-FT torque
Sharper throttle response
Improved power delivery and drivability
Refined EQ-Boost integration
Factory-level safety logic retained
Actual gains vary based on fuel quality, ambient conditions, factory baseline, and vehicle-specific limitations (including CPC logic/strategy where applicable).
Why AMR Beats “Module-Based” Tuners
Many brands rely on add-on modules or limited-function handhelds that only “trick” signals or offer partial control.
AMR delivers direct ECU programming, OEM-level map access, and tuning designed to work with real-world conditions and dealer service workflows—including compatibility with dealer updates.
This is real calibration—not signal manipulation.
