For the moment Im fitting Megasquirt to my S2.

The topic is about the fuel pressure. I know that standard (MFI) have a fuel pressure somewere around +5.5 bar. But what about fuel pressure in a EFI engine? I read on internet that 3 bar is the way for EFI. Is this true?

The thing is Im thinking of fitting a after market fuel pressure accurater. I want to know what you guys recomend in feul pressure.
