fuel pressure ?????
 
I just installed 24lb fuel injectors and a new mass air meter and I have a new adj. fuel pressure reg. and I'm waiting to install it till I'm sure I know what pressure to set it to. Any ideas of what I should set it to.
Thanks

Set it at 38 psi with vacuum line off and forget about it. Your ecu will adjust the injector pulse width accordingly from there.

Thanks.....but won't that create a lean condition, isn't the stock pressure 48psi. I may be wrong with the stock pressure.

Technically I believe the injectors are rated at 39 psi. Usually the stock pressure is 40 to 44 at WOT (no vacuum). They usually run stronger when set at 38.
