Mercedes-AMG GT63 / GT63 S (C192 · M177) — Stage 2 ECU calibration delivered via YPG Flash, our remote programming service built for GCC performance car owners.
Stock output: 577HP (GT63) / 630HP (GT63 S). YPG Stage 2 delivers 727HP (GT63) / 780HP (GT63 S) — a gain of +150HP over stock with catless downpipes and high-flow air filters installed. Competitors using generic remap files for the M177 at Stage 2 typically claim 100–115HP. The YPG calibration exceeds that by 35HP+ through aggressive boost mapping, extended torque management across the full RPM range, and fuel delivery optimization calibrated for GCC temperatures and 98RON fuel.
