What tune do you run with these and the 02 bungles are still in tact from the factory?

You don't have to run a tune to get solid gains but it does help.
IMO there isn't a big difference in which tune it is.

The primary O2 stay at the exhaust manifold (header) along with the EGT sensor.
The secondary O2 have to be relocated to the section 1 CATs.

There are several treads on this topic.

I was running the Autowerks tune, but as mentioned I don't think it matters much. The tune probably adds 5-7hp on top of the 20-25ho gain from the header. Running the header alone is a big gain and you can certainly feel it.
