Anyone have a tuned LT1 that can let me know what the DFCO values are?

I am trying to make some sense out of them and not doing terribly well.

Mainly DFCO Disable RPM Decrease Threshold, mine is set to 2500 rpm/sec. So, does this disable if the engine decreases rpm at faster than 2500 rpm/sec or slower? I have seen some tunes at 1250 rpm/sec.

Mine still has a 2-3 second DFCO delay that drives me batty that I want reduced. I can't find a way to do it. Anyone know?

I have looked around may forums, but haven't found much.
