anyone know what to set the fuel pressure for fpr? im running a greddy twin turbo kit.

 

set it to 52 or so without the vacuum attached

 

aps reccomends 58. idk what to go with >.<

 

Then why ask??

 

cuz it seys it supports 600whp. im only @ 400ish

 

I am running 44 or so with the vacuum attached which is about 54 or so without the vacuum attached and running those power levels, APS uses that high of a fuel pressure because they use it to run smaller injectors and make them flow like bigger injectors at lower fuel pressures.
