What should my fuel pressure be at idle and at WOT. 42 LB inject, p600b procharger 8psi, in line fuel pump that comes with procharger, stock in tank pump, also below listed mods????

 

The stock fuel pressure is 43.5psi (GM accepts 41-47psi), with no vacuum compensation. At idle, the typical NA setup will run 4-8psi lower than that, because of intake manifold vacuum.

Does your setup include a boost referenced fuel pressure regulator, or an FMU? Typically, at WOT your fuel pressure with a compensated FPR will be 43.5psi + boost.... example, at 8psi you would see 51.5psi at WOT. With an FMU, the pressure will increase based on the FMU "ratio" setting of psi of fuel pressure increase/psi of boost.

What did you tell your tuner the "base" (no vacuum, no boost) fuel pressure would be?

 

Im new to the whole F/I setup. Im going to install the procharger and getting everything in order i.e gauges etc....

Im not using FMU because I will be having 42LB injectors. I have not discussed tuning yet with PCM4LESS but im prob going with a dyno tune once installed. What's your take with the fuel regulator???If im not using an FMU what else should I do??

 

Heres my thread i have that will go into detail after i installed 42lb, removed fmu and had it tuned by pcmforless. I assume this is not typical but there is some useful info that should help. The wideband is on my want list right now.
