XperTune Performance Software
XperTune ECU software for the E3 Cayenne GTS and Turbo's 4.0L twin-turbo V8, not compatible with hybrid models. Fabspeed's dyno figures for the GTS show a jump from a stock 420whp/448 lb-ft to roughly 600whp/526 lb-ft. The ECU is mailed in for reprogramming rather than tuned in the car, and Fabspeed keeps your factory settings on file so it can be flashed back to stock for a small fee at any time. Shipping costs to send the ECU in are the customer's responsibility, and Fabspeed returns it via whatever method it was sent, typically within 24 to 48 hours of receipt.
Frequently asked
Which cars does the XperTune Performance Software fit?

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.
Does this fit the hybrid Cayenne E-Hybrid?
No. Fabspeed explicitly states this tune is not applicable on hybrid models.
Do I need to send in my whole car?
No, only the ECU — you'll get an email with instructions once you've ordered, and it typically comes back within 24-48 hours of Fabspeed receiving it.
Can this be reverted to the factory tune later?
Yes, for a small fee — Fabspeed keeps your original ECU settings on file.
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.
