M-Engineering has been at the forefront of Porsche ECU tuning, and has spent countless hours of research and development to provide reliable performance improvements.

Our M-Tuner Calibration Suite will allow at home OBD flashing, no ECU removal is necessary. Our software also features the ability to read and clear faults, datalogging, view live data, and flash back to stock at your convenience.

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. Our Stage 1 tune results in an increase of approximately +16whp & +10ft-lbs tq on 91 octane.
