The car is a 2014 Camaro SS, the combo is nothing new.

The STFT at idle are split B1S1 reads +3.1 or so B2S2 reads +30.5 I have attached a scan and the tune. Any help would be great.

If you know the injectors are good, start with the O2 sensors or look for a vacuum leak.
I know the injectors are good, I checked and confirmed no vacuum leaks. The strange thing is the problem is only at idle, during normal driving they are fine.
Check for vacuum leaks and misfires

As I said in my pervious post, I confirmed no vacuum leaks.
any chance the o2 is getting cold and drifting? it's a old obd1 issue that we used to see with 1 wire o2's in headers. maybe the heater in the o2 died?
just throwing things out
I had a similar issue. It ended up being an exhaust leak.
Similar issue in a different car, was an exhaust leak.
