XperTune Performance Software
XperTune performance software for the 955 Cayenne Turbo and Turbo S 4.5L V8, delivered through a handheld tuner that plugs into the OBD-II port rather than requiring you to remove and mail in the ECU. Fabspeed's dyno tune takes the Turbo from a stock 450hp/460 lb-ft to roughly 506hp/521 lb-ft, and the Turbo S from 520hp/530 lb-ft to about 577hp/589 lb-ft. You read your car's stock data with the handheld, email it to Fabspeed, and get a custom tune back within one to two business days to flash onto the vehicle. The same handheld can flash the ECU back to stock at any time, no return shipping required.
Frequently asked
Which cars does the XperTune Performance Software fit?
Fits your Cayenne Turbo / Turbo S (4.5L Twin Turbo V8, 2002-2007). Fabspeed lists this piece for: Porsche 955 Cayenne Turbo and Turbo S 4.5L V8 (2002-2007). 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 my ECU away to be tuned?
No. This uses a handheld device through the OBD-II port, so tuning and reverting to stock both happen without removing anything.
How much power does this add?
Fabspeed's dyno figures show roughly 56hp/61 lb-ft on the Turbo and 57hp/59 lb-ft on the Turbo S over stock.
How long does it take to get my tune?
Typically one to two business days after Fabspeed receives your vehicle's stock data.
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.
