I would suggest a pnp MS setup along with a 1:1 FRP. Static fuel pressure isn't ideal for boosted setups, but of course that all depends on the tuning.
no. it's 1:1. all standard FPRs are 1:1. this keeps the fuel pressure at the injector constant relative to manifold pressure. it's necessary to keep the fuel output linear which is what the computer will always expect.
a RRFPR would have a ratio like 1:5, 1:8, etc. this makes fuel injector response non-linear, which is a bad idea. RRFPRs haven't been a good idea for a decade at least. They were a decent band aid solution before you could build a standalone for $200 but they're pointless now.
No shit, that's why I suggested a 1:1 because the stock unit looks almost identical to all the old VW RRFPRs I've messed with, so I just assumed it was rising rate.
