3 bar standard, without mapping its pointless adding more pressure.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

not at all, basically unless youre running lots of boost there's no point running more fuel pressure.if you need more fuel get bigger or more injectors. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I replaced mine at 160k miles as you could smell fuel on the vacuum hose. I guess they start leaking sometime.As long as you don't run out of fuel flow / don't get your injectors to work on 100% during mapping I would just use the standard 3 bar FPR. The higher you go pressure-wise, the more you need to lower the time the injectors are powered to get the same amount of fuel into the engine. -> you lose time resolution. pug_306 wrote: 3bar is fine for standard engines buddy. I think late xsara vts was 3.5bar Ryan, is it the same map with the 3.5 bar FPRs? |

yeah the phase2 xsara was quite a step forward in ecu's, twin lambda system as well as different injectors though mostly the same, they are much better on fuel than the older MM1AP10 ecu.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |
