Just want to know what you guys are running for fuel pressure. It seems like my buddies GSR turbo is running rich at 52 psi.

What do you guys usually run at?

 

It depends on the computer and if its chipped. I have my FPR set to 37-38 psi with vaccum line attached @ idle. I also have a mugen ECU chip.

 

Stock fuel pressure is 42psi with Vacuum attached.
Thats what I am running.

 

i run 38 psi w/ vaccum reference at idle. p28 tuned to 13.0:1 with hondata at WOT

 

Damn all I know is he has a 10,000 rpm rev chip in a B16 ecu. At idle he is at 50-52 psi and I know when we rev it the pressure sky rockets to 60+. He has a type r in tank fuel pump and a BBK inline fuel pump running Accel 310cc injectors. Should we adjust the AEM regulator down to 42-45 psi at idle and see how she runs cuz right now at 5-6k rpm it shudders bad and clears up after a bit. I figured it must be flooding when the v-tec is kicking in at that rpm range.

 

My car must be messed up... im runnin at 47psi vaccuum attached and 50 without. I dont understand how it can be soo high because everything in fuel system is stock. any suggestions besides FPR?
