does anyone know if there is any benefit to bumpin up your fuel pressure a couple pounds?......and whether or not the 1/4" injector spacer has any actual "real" benefits as well?

on what motor? spacers do only on tbi motors

yeah its a 5.7 tbi.......wondering if bumpin up the fuel pressure a couple psi.......and adding the spacer will help?

i added both the injector and tb spacer to mine, as well as having the edelbrock manifold which is almost like aspacer in itself. then i shoved a quarter under the pressure spring, helped alot.

Injectors. GM released 5 sizes of TBI injectors (actually more but those are the important ones) 40lb/hr for the 4.3L and 5L engines, 55lb/hr for 350 engines, 65lb/hr for cop car 350 engines and (80lb/hr and 90lb/hr) for 454 engines. From tbichips.com

I've read that as well on there.
