i got a cosmo fpr, i can't adjust the fuel pressure with this thing. Or i can't adjust it enough. I've got 440cc injectors, 255lph intank pump, stock gsr, and running a basemap of uberdata. My car runs too rich. I can't figure out what to do. Oh the fuel pressure is stuck around 25psi at idle. Anyone know what i should do? Is the fpr messed up? The gauge on it has a bubble, but i figured the regulator should work. Please help. Im 45 mins north of west palm beach if anyone has any knowledge bout this, is in the area, and is willing to help me. Thanks.

 

think i should put my stock fuel pump back in?

 

your static fuel pressure should be at ~43 psi.

you need to adjust your fuel map within the gooberdata software.

 

Did you account for the 440's in the Uberdata map?

 

yeah, i entered 440 injectors into uberdata and set the fuel modifiers. I dunno what to do. Im bout to try to sell my injectors and put on an fmu and the stock injectors.

 

static fuel pressure, is that with the vacuum line disconnected? I can't adjust the pressure with this shitty cosmo fpr i got.
