if your o2 sensor is BAD re-enabling it won't fix the problem. Without an a/f graph you have no idea what they tuned it to. If it's 12:1 you won't pass. If it's 15:1 it won't pass.
Are you sure they "tuned" it or did they just do power pulls. How long did it take etc. If it was tuned they should provide you an a/f graph so you know where your car is tuned to. Not providing that info is not informing the customer of the job/service they performed.
They may have just forgot to put it on the sheet so I'd call them and ask for a copy with the a/f plotted
