Not sure how much info is needed to answer my question but I'm running a 1999 Turbo Busa with BEGI MR2035 FMU and stock injectors...

Can anyone tell me what the fuel pressure should be at zero (0) vacuum? Thanks.
 
Dang, fast reply cdh :laugh: I was getting ready to edit my original post. I only asked because I vaguely recall reading somewhere that it would already be higher than the fuel pressure at idle... but I'm not sure I remember correctly.

So then zero vacuum is the point where the fuel pressure should just begin to rise?
