M-Engineering flash for the MG1 Cayenne. *2025+ models of the Cayenne variant include the newer "locked" H80 MG1 ECU's. These new ECU's have a longer work flow to unlock and flash hence the longer downtime and added costs*

Adjustments are made to improve the throttle response, remove top speed limiters, adjust air/fuel ratios, and modify ignition timing and much more to improve the overall driving performance of the 4.0L twin-turbocharged engine. 

Our Stage 1 tune results in an increase of approximately +85whp & +110ft-lbs tq. Expect around 20+ more whp and torque with Stage 2. Power gains vary depending on model/trim of Cayenne. Email us for more information. 

Available in Stage 1 or Stage 2 configurations for 91, 93, or 100 octane.
