XperTune Performance Software
An ECU tune for the Bentley Bentayga's 6.0-litre W12 or 4.0-litre twin-turbo V8, sent to Fabspeed for bench flashing rather than installed on the car. This isn't a physical, shipped item: you post in your ECU with a completed information form, Fabspeed reprograms it within 24-48 hours, and ships it back the way it arrived. Fabspeed's own dyno figures for the W12 show stock at 522hp/668tq rising to 622hp/798tq. Your stock settings are kept on file so the ECU can be reverted at any time.

Can I go back to the factory tune later?

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?
