Default FUEL PRESSURE...I need an answer! Thanks!

Ok, i just got a SARD Type R Adjustable Fuel Pressure Regulator. I am running stock injectors and stock fuel rails, but i have modded the rails to run in parrellel rather than series. ( I doubt that makes a difference) I am running 5 psi on a Legacy Turbo setup. What should my IDLE fuel pressure be, and what should my On boost Fuel Pressure be? I have two gauges, one reads PSI, and one reads a weird metric reading. I just want a breif summary of what pressure i should be looking for!

Idle should be around 34-35psi... on boost, well... you better ask someone else, fuel pressure and I don't get along too well.

The SARD unit is just a 1:1 unit, is it not? In any case, you will probably want to bump your fuel pressure up by atleast 6:1 on CA gas. Blaster88 got away with 4:1 but they also have an extra 2 points of octane. The math works out at this with 5psi of boost: 5psi x 6 = 30 psi. So you need 34psi + 30 psi (give or take).

what stimpy said. it is very bad to be running any form of boost with stock injectors and no RRFPR. 1:1 is just NOT enough.

There are two types from SARD, a regular one and a Type R one, The type R one is a RRFPR and the regular one is just a 1:1.

This link have the picture of both the regular and the type r model and a little write up.
