The real reason they think they are better (the ford/bosch injectors)
is a few on the fourth-gen list say they are better because they don't
lockup at high fuel pressures (60+psi), and the others seem to notice
and believe the 24lb injectors will be better for all applications
even their application that is not using high fuel pressures.
On mine I swapped 22lb GM (93 f-body LT1) out for 30lb ford svo
injectors mainly because I was concerned about not having enough fuel,
and according to the kind of pulsewidths I was running on the 30lb
injectors (7.3ms) I would have required 9.9ms (at 6000rpm-well past
lockup of around 9ms) and would not have had enough fuel. I may also
have been a bit on the lean side at 7.3ms on the 30lb injectors.

I did not notice mine being louder, but the 93 is a batch fire car (it
fires each sides set of 4 at the same time).
