Default Why are my RPM's dropping?

When i push in the clutch to coast, or to come to a stop, I'm assuming the DFCO is kicking in and the rpm's drop. That's great and all, and it seems to kick in at the correct time and level.

My problem is that when DFCO kicks in, the RPMs drop all the way to 400-450 then climb up to my idle point (825rpm). It takes about 3 seconds to climb back up. This isn't a HUGE problem and it sounds pretty cool at 450 rpm, heh, but if it happens when I'm coasting around a slow speed turn, especially on a cold engine, it nearly stalls (and did stall today).

Any idea why they drop so drastic? The DFCO is set to turn OFF (fuel back on) at 1000 rpm.

Is this some sort of throttle follower setting or something?

Thanks folks!
