Anyone know if the European G.Voyagers Series4 are programmed for 95 octane petrol/gas? When I had my last American cars, both Fords (95 T/bird and Lincoln Mk8), they were set in the engine management for 91 octane from the factory. Putting a Superchip on each gave an increase in performance. My 2004 GV doesn't like the new to UK E10 so I'm using E5 Super instead.
