So I’ve googled my butt off and can’t find this answer. My car has cat delete, and the rear o2’s are just in the x-pipe plugging the holes. Does that mean the egr is turned off in the tune? I bought the car this way and was told it has an sct tune from the 2nd owner who didn’t put the tune on the car. I’m changing header gaskets and am thinking of deleting the egr. Any insight would be appreciated!

Depends.
Sct had a lawsuit, the feds came down on them.
with sct you can no longer turn off egr, rear cats, or any emission related things.
Not even the tuner can, nor a pro racer software owner.
So it depends on when the tune was put in the car, and if it was updated?
Hard to know with out looking at the tune.

having to deal with all this with a new motor I will soon install.
All the emissions crap will be back on it.
