Am about to fit a fuel pressure reg but was wondering wat pressure i should set it to.i only have 380 injectors but am sure i read on here that u can set the fuel pressure n they can run like 440's but i can fibd it again.i have a 1998 impreza estate with sti heads n cams,mauhle pistons sti bottom end,sti inlet manifold,apexi avcr,equall length headers 3"tubro back,fmic.probly more but lost count.lol.iv got a td05 to go on aswell.so wat would b a good pressure 2 set it 2?

 

Unless your going to be getting it mapped? You can only really set it to standard pressure. 3 bar with vacuum disconnected i think from memory

 

As you comment about fitting a td05 you will be getting the car mapped due to different turbo characteristics. So fit the AFR set it to 3 bar with vac pipe disconnected and the mapper can adjust it if required.

 

Yea will be gettin it remapped after fitting turbo.ok thats wat il do.thanks for the help.
