Default Are all LS1 injectors the same size?

I was looking through some stock tunes and noticed that different years have different flow rate settings. Are they all 26 pound or not?

Really?

IIRC, 98s were 28#, 99-02 was 26# and the GTO's were 28's.

In-correct.

98 had 28s, 99 and 2000 got 26s, and 01 and 02s went back to 28s.
