From the little I know of tuning(written only one from scratch), those maps are quite safe.
O2 is only active over 1300 because of how the cams operate at idle, the reading will be nowhere near correct. The incoming wash is actually partially sucked through the exhaust before the exhaust valve closes, which gives a false reading.
It should still read, but it will ignore it.
Where did you get your values for the VE and spark tables? Are they moderately correct for your setup?
S-D tunes have no capability to compensate for changes in hardware, so every tune is different. They can still be close, though.
Make sure to model your injectors properly (dead time, size, fuel press, impedance) otherwise the lambda control will be off the wall, and totally wrong.
Make sure your air intake temp sensor is calibrated correctly, because S-D tunes rely heavily on air temp.
Make sure you have inputted a correct value for the cam/crank sensor input offset, so it knows accurately where TDC is.
There should be a general engine settings page, I've never used tuner studio, but you need to tell it number of cylinders, rpm limits, displacement, idle setting, etc etc etc. If you don't know what it is, leave it as default, and then find out.

I don't know it works exactly with tuner studio, but most engine sensors are 5v sensors, and they have a range they respond to, but in some sensors, 2.5v may be the middle, but in others, it might be 3.2 or something, so you have to tell it what the voltage curve is.
S-D is speed-density. using MAP as load versus RPM.
