Frequently asked
Does the XperTune Performance Software fit my Cayenne?
This listing is specific to the Porsche Cayenne (958.1). Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
Exactly which cars does this fit?
Fits all Porsche 958 Cayenne 3.6L V6 Vehicles (2011-2014)
Do I need to remove my ECU to get this tune?
No. The XperTune handheld interfaces with your car's OBD-II port so you can flash the tune yourself without pulling the ECU or mailing it in. If you'd rather not flash it yourself, Rennen Motorsport or an authorised dealer can do it for you.
What power gains does Fabspeed quote?
Fabspeed lists the 958 Cayenne V6 going from a stock 300 HP / 300 TQ to a tuned 320 HP / 318 TQ.
Can I switch back to stock?
Yes, Fabspeed says you can use the handheld to flash the car back to stock at any time, then reapply the XperTune later.
What do I need to use the handheld?
Fabspeed notes you need a PC or Windows computer to upload your vehicle data, as Mac OS is not supported, and the handheld device pairs with only one vehicle.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
Every enquiry, whether it's one part or a full build, starts with a free consult. We confirm the exact spec for your car before anything is quoted or ordered.
