O2 sensor
All "deleting" a rear O2 really is doing from a PCM calibration stand point is having the PCM ignore any DTC errors it sees with them. You can leave them plugged in or remove them completely if the DTCs for them are set to not report an error. Makes no difference. What do you plan to use to tune a 97 LT1? There are only a few options and most tuners don't have them.

I'm taking it to get dyno tuned by a shop here in Colorado Springs not sure what program they use but they are the only one in town that will or can do it.
I'm rebuilding the motor and all exhaust so I'm going from stock exhaust to long tubes and y pipe and it only has two o2 sensors on the whole system so I was just confused on weather or not leaving it unplugged would work or not
