XperTune Performance Software
XperTune performance software for the Porsche 957 Cayenne V6 3.6L (2008-2010), tuned through a handheld device that interfaces with the vehicle's OBD-II port rather than removing the ECU for bench flashing. You read the stock data off the car with the handheld, send it to Fabspeed, and get a custom tune back within 1-2 business days to write onto the handheld and then the vehicle. It reprograms sensor inputs, air/fuel ratios and boost pressure, raising the factory-rated 290 hp / 284 lb-ft to a tuned 312 hp / 300 lb-ft. Because the handheld pairs to one vehicle, you can flash it back to the stock map at any time without removing or shipping the ECU.
Frequently asked
Does the XperTune Performance Software fit my Cayenne?
This listing is specific to the Porsche Cayenne (957). 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.
Do I need to send in my ECU?
No, this handheld tuner reads and writes through the OBD-II port, so there's no need to remove or ship the ECU.
Can I switch back to the stock tune?
Yes, the handheld device can flash the car back to its factory settings at any time, and back to the Fabspeed tune again.
What do I need on my end to use it?
A Windows PC to send your vehicle's factory file information to Fabspeed by email; Mac OS is not supported.
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.
