Most of these newer injectors flow higher in the low pulsewidth slope, which the $EE mask doesn't support so everyone just zeros it out. However, I've never seen mine idle below 1.4ms while it was a 355 / 5.7l.
No Idea.
The Web page publishes data for them.
Data sheet in the box is slighty different.
And the "Flow matched set aren't all the same value on the sheet. SN on injectors don't match sheet.
Seems to be the norm.

42lb
42.5lb@3bar
44.1 @ 47.psi
Flow rate is now currently set at 38.511 with VE's to match as it was very lean.

I'd HOPE a company publishes correct info but who knows.
I got "data" for the slope.
I had to write software to Interpolate it to get it to fit our tables, the same as the Voltage offsets and fuel pressure vs flow rate.
I had "slid" the table along to add more fuel down low for the last few runs.

That worked somewhat for the Black Ops injectors.
I read on Tuner groups where you dial in 14.7 AFR and that's it.
I feel this is trying to balance on the head of a pin.
Keep going fatter with no change until suddenly it's pig rich 12-13 but nice and stable
or
lean it back a bit & it's 15-17 AFR and erratic.
