Dave's comment would make sense. I don't know what the NA FPR is rated at, but Trent Saab (http://www.trentsaab.co.uk) sell a FSE RRFPR, which according to the blurb from FSE needs no re-timing or replacement injectors. Abbott Racing (http://www.abbottracing.com) OTOH state that the standard FPR is between 2.6 and 2.8 bar and sell a replacement FPR rated at 3.3 bar (not rising rate). Their website states the reasons, so make your own mind up. I used the FSE RRFPR on my old Punto GT and the performance increase, while slight, was noticeable. I'll be fitting one of these to Orca.
