Overview

M-Engineering's calibration for the 2025 and later Cayenne covers the S, GTS, Turbo, Turbo GT and Turbo E-Hybrid with the locked H80 MG1 ECU. It improves throttle response, removes the top speed limiter and revises air/fuel ratios and ignition timing.

M-Engineering quotes approximately +85whp and +110 lb-ft at the wheels for Stage 1, and around 20 more whp and torque with Stage 2. Power gains vary by model and trim. Stage 1 and Stage 2 calibrations are offered for 91, 93 or 100 octane.

Installation is a bench procedure: the ECU is sent to M-Engineering HQ and returned, typically about 24 hours after it arrives. M-Engineering notes the locked H80 MG1 ECUs need a longer workflow to unlock and flash, so allow for extra downtime.
