Idle Tuning

The new tune is in. I haven't driven it yet, but it started right up and idled much better than it has been. I turned the fuel pressure back down to 59 PSI with the vacuum hose off. Is that correct, or should it be 58 PSI?
I changed the Desired Idle Speeds to 600, but it's still idling at 700. Is there another table that affects the idle speed? I did make sure that the idle stop screw on the t-body wasn't holding it open. The bleed screw is closed as well.

Like I mentioned above, even with the minor fueling and spark adjustments I made, that 6.0 is going to idle perfectly with that mild cam. The PCM will make it's own adjustments as well which will help things.
