O2 sensors + Diablo Predator tune + dyno = ?

So here's my situation..

I have SLP LTs, SLP O/R X-pipe, and the Steeda cat-back.. I WANT A TUNE!! Everybody is telling me to have the o2 sensors tuned off. What I'm trying to figure out is that when you get this tune does it just make the o2 sensors stop reading? Or does it adjust what the computer thinks the readout should be so it stops throwing a code? And if I got o2 simulators do they just tell the computer what it should be (the same reading as stock)?

Also I'm getting on this tuning done on a dyno by a diablo predator next month, what should I do when I go? Run preminum gas? anything else? Thanks
