Default Flow Matched Injectors

I'm kind of spawning this off of ChillinMichael'* post in for sale and trade section.

What do they do for performance for a near-stock setup?

They equalize fuel distribution between all cylinders which improves performance, reduces KR and improves economy.
Basically, the oxygen sensor only reads the end result from all 6 cylinders, so if one injector is flowing differently than another, the O2 sensor can't tell. The PCM can only correct for the whole.
So, if you had one injector running really rich, it would lean out your other cylinders or vice versa. Flow matching eliminates this possibility.

That'* my understanding anyway. I'm sure others can elaborate too.

You nailed it. If each exhaust runner had it'* own O2, you wouldn't need it.
