Default 1992 LT1 injectors question

I know 24lbs rated injectors is the standard for the 92 lt1.
I came across a good deal on a new set of Bosch but are rated 22lbs, would the 2 lbs difference cause a problem? would it cause a lean mixture problem

1992 OEM is 22#. I got 23# Bosch III from FIC and they are just fine.

In a word "YES".

I have datalogging that shows the injector pulse width on my 92 was 100% at 6,000 RPM (only engine mods at that point were long tubes, and disconnected EGR).

So - substituting smaller injectors can be a BIG problem !!!!
