My LS6 swapped 944 is getting P0133 and P0153, the car has run fine for quite a while with only P0300 bothering me, I have already swapped the front O2s but the codes are still coming. The O2s are in the headers about 2" behind the 3 bolt flange, I thought the codes could be caused by exhaust leaks.

I done some logging with a Calc Vet pid selection, this has me stumped, has anyone had this issue and found an electrical or tune issue?

I have attached my tune and a log taken, I drove the car for around 10 minutes then the my CEL lit up, the CEL lit up while capturing the attached log.
