Uh, no.

Stock flow rate for for 94-97 LT1 injectors is 24#, while 93s use 22#.

I'm going to assume you're talking about rail fuel pressure. You need a fuel pressure test gauge that attaches to the Schrader valve at the back of the intake manifold.

Fuel pressure should be around 43psi with the key on, engine off, then drop slightly with the engine idling and gradually increase with throttle position.
