Default basemapping for boost and 450's

I am writing a basemap for my setup, and i had a few questions.
Heres the setup:
bored .020 over
stock cast pistons
T3 63.60
ebay intercooler
Crome v1.2.5
I got it running good with the 240cc injectors when it was na, I had to add some fuel to the P72 map to get the AFs down to around stoich and stop the breakup in the high rpm range.
now that I installed the turbo/dsm 450's, I took this map that ran well in na mode and added fuel tools/boost to it. I set the boost ignition retard to 1deg/lb boost and the boost efficiency to 180% as Xenocron suggested in his Crome writeup. I set the battery offset to DSM 450s. I started the car, and my wideband was reading zero in Freelog. I used the software that came with the wideband (Innovate LC-1) and it was reading an AF ratio of ~7-1 in idle! Is this normal for a map described above to be so rich? Would the car even run at that level, or could it be that my LC-1 got screwy during the install?(it worked fine before the turbo). If the battery was disconnected, do I need to recalibrate the o2 sensor? Thanks in advance for your help.

Did you add fuel tools and scale it to 450's? If you didn't, it still thinks you have the 240's, but in reality it has 450's which means its pouring out a lot more fuel than it should be.

Yeah, Its all scaled correctly, after thinking about it, I suspect that my completely dead battery has something to do with it. I am going to trickle charge it overnight and try it out tomorrow. Judging by the freaky behavior of my wideband, I think that this may be the issue.
