[QUOTE="drexchan, post: 384840, member: 6936"] have you guys tried out coupling the A-FPR with a FMU? I found that it gives a comparetive response (if not better) even with pressure set to be lower than stock. FMU - fuel management unit, also called RR-FPR (rising rate FPR), to boost the rising of the manifold pressure at a factor >1. Stock FPR and most of the normal A-FPR gives a 1:1. Meaning 1 psi increase in manifold increases 1 psi in the fuel rail. FMU or RR-FPR give a 1:1.xx boost. Meaning it increases the fuel pressure at > 1x than each psi increase in the manifold pressure. See the attached diagram in the bottom of the post. The vacuum hose from the A-FPR is connected to the FMU before going into the manifold. Another vacuum port is Tee'ed to the PCV. mine is a denso unit from japan. Used, quite old, non-adjstable but still gives a boost. Well.. mine is NOT exactly a FMU coz it has a small filter mounted at the top (which FMU don't have). I dunno what's shouls i call it so just put it as a FMU. I lowered the idling pressure to 32psi (stock 36psi). The combination seems to behave pretty well. Will keep monitoring the performance and FC... [/QUOTE]
