I have an LT10 setup on my 13B NA. I had what I think was a ping at 6K rpm. I reduced my timing advance to +10 (from +25) and it seemed to help. I still get pinging above 7k. Is there something else to do to be able to keep the advance set to 25 or am I stuck? For instance, should I be adding fuel in the rev range to stop the pinging?

First thing.
Check your base timing.
Get a timing light out and make sure its all up to scratch.
Car shouldnt ping with 25 degrees advance in it if base timing is correct.

What kind of boost and what map sensor?

No boost(N/A) and factory 2.5 bar map sensor.(hasnt been stated otherwise and wouldnt make a difference in this case).

Right didn't see the NA for some reason.

Is timing lock off?

What kind of split timing are you using?

If it was on it would stay on zero degrees all the time hence it wouldnt ping at all.(or ping less).
