Default Car falls on its face @ Stop signs

When slowing down to stop the car will stall if I don't hit the gas. Where should I look to fix this.

Mods:
'02 Z28 M6
TSP 233/239 .603/.600 112 LSA (Just installed)
LT w/ cats to Cut-Out
30# Injecters
Pulley
Lid

I have HPTuners and Idle is pretty good at start-ups. Here is some of what I've done:

Set TB Screw
Idle RPM 875
VE 1200> 60/80/90%
Timming +2 600/800 RPM .08-.32 / +1 1000 RPM /08-.32
IAC Park Position 68*< set to 21.00

Thanks!

When mine was doing this, I had not adjusted for the injectors. I simply told him what to adjust them to. Another forum member showed this to me, I would have never figured this out, hell I'm still learning to tune. Closer have you swapped injectors?

No, G5X3 in an 04 GTO, stock injectors. No tuning yet, waiting for Hp Tuners to arrive this week.
