Default tuning after datalogging session

so, I've been messing with my tune for awhile........ started using BRE and the autotune function works well, but I don't have a laptop that has 2 usb ports and it sucks to use a power inverter. anyway I'm not complaining about that.

I just got back from tuning in vac. a little. Its really hard to watch all your gauges and tune even with ostrich. BRE has a really good datalogger and I'm going to log a session of just driving around normally tomorrow on the way to work. My question is, that 8.6 increase the a/f ratio 1 point fact or not? I don't remember where I seen that. Any other tips on street tuning. I have all the hardware, but I'm still having a hard time. The a/f ratio is no where near a steady ratio across the rpm range.

it's a low boost setup, super small turbo. I set boost retard to -.60, no vtec, no two stage boost or anything.

I was playing with BRE last, night and they actually have a feature that show the difference in the dataloged a/f to my target a/f's, so I'm going to have to try that. BRE for obd0 is the ---- I'm almost completely not using TE anymore.
My original question was in TE if say a value in the fuel map is 2.58, how high would I have to change that value to, to get the a/f's to raise 1, to say 13.2 to 12.2.
