Just to throw my $0.02 worth in on this one. The 24# injectors may be
application specific as Terry noted on his findings. On my V6, the 19# were
too small as they were showing a 15.8:1 A/F ratio (almost 16.0:1 at times)
with the 12:1 FMU plate and the 24# showed a 13.2:1 with the 10:1 FMU Plate
(i'm running the 12:1 Plate again since I switched out to the 9# pulley and
it's still at 13.2-13.4:1).
Confused yet? ;)

Unless you're running a SC or have done major mods to the engine, yes,
the PCM tables have to be changed. Look at my web page for all the
mods I've done to my engine. The 24's were still too much. I was
running below 10.0 A/F at WOT. Going back to the 19's brought my A/F
up to 12.0 and increased my rwhp from 242 to 250. A few minutes later
I removed the Quick D intake and went from 250 to 258. Putting on a
K&N Gen II, I still pulled 258.
