Running Rich ok...so im runign rich. It smells really strong in my gas and i went form like 16-17mpg to like 14ish. car is tuned for my mods except the catback.

anyone? Im about to goto the shop in just a few hours. I would really like ot know what the upstream and downstream O2s are supposed to be reading. Also is there anyway to check if the o2 is bad?
here is the info i gathered form the scanner at idle.

ok with all of waht given, would you say that the o2s are both dead? I have all of the emissions removed and a gutted cat. Also do all of these numbers seem about right? Any information would be great! thanks in advance

The reading from the O2s should fluctuate rapidly between ~0-900 at idle and cruise. They are most likely working if it does. You can tell they are dead if the reading consistently stays at a certain value. The only time that should happen is at wot and right after startup when the engine is still cold.
The only thing kind of odd about that data is the split blms.
