MSnS 3.0 super rich??

so I've been running pretty much moby's setup on my Z31 with corrected variables to fit the V6 and a few minor tweeks to the VE tables, the car ran great just a bit rich, as a matter of fact it dyno's 315 whp and 416 lbft TQ just a few weeks ago, I just noticed I had the incorrect setting in easy therm, I went to upload new settings and selected the wrong code version, wiped out my ecu and I couldn't find my backup

 

after downloading and reconfigurings everything, the car will run but super pig rich, as a matter of fact it will flood itself out and die, unless I unplug the fuel pump in which case it'll idle forever, just can't rev without fuel pressure, I've verified my static fuel pressure is about 35 psi and with the pump off it's zero, if I pinch the feel line or unplug the injectors it dies so it appears the injectors will run fine with low to no pressure and in this case is siphoning the fuel from the tank?

 

I set this thing up years ago and my memory isn't the greatest, am I missing something where I tell MSnS what the static pressure is? the req fuel comes up to 8.0, what am I missing here?

problem solved, sleep deprevation makes the obvious excape me, I never got those therm values updated so the cold start enrichments were flooding the engine, I disabled the enrichments and not running like a champ
