Fabspeed Porsche 958 Cayenne Turbo / Turbo S XperTune Performance Software (2011-2014) FS.POR.958T.ET

Achieve maximum power gains of over 99 whp and 140 ft-lbs while maintaining reliability and drivability with the Fabspeed ECU Tune for your Porsche Cayenne. This easy-to-install tune is designed to enhance performance without the need for traditional ECU bench flashing. The included handheld device interfaces with your Cayenne’s OBD-II port and your computer to complete the tuning process seamlessly.

Tuning Process:

1. Read Stock Data: Connect the Handheld device to your Cayenne via the OBD-II port to read the stock data.
2. Interface with Software: Connect the Handheld to your PC/Windows computer (Mac OS not supported) and email the data to Fabspeed Motorsport.
3. Receive Custom Tune: Fabspeed uses the data and vehicle information to create a custom tune, which is emailed back to you within 1-2 business days.
4. Flash ECU Tune: Write the Fabspeed ECU Tune to your Handheld, then flash it to your vehicle using the Handheld device.
5. Enjoy Increased Performance: Easily revert to the stock tune or reapply the Fabspeed ECU Tune anytime with the Handheld device.

Power Gains:

• Stock: 449 whp / 515 ft-lbs
• Tuned: 536 whp / 620 ft-lbs
• Peak Power Gains: 86 whp and 105 ft-lbs of torque
• Maximum Gains: Over 99 whp and 140 ft-lbs of torque at 6000 RPM

Tuner Notes:

"Porsche left a lot of room for power gains—140 ft-lbs of torque to be exact. The results are outstanding, making the Cayenne feel quicker and more agile, akin to its 911 counterpart. The throttle response is smoother, and the car feels more refined. For the best results, consider pairing the ECU Tune with our Secondary Cat Bypass Pipes to improve turbo breathing and boost levels."
