Bingo.
For whatever reason tuners seem to delete this table without asking?!
After driving mine home after pulley & tune, I was like WTF with how quiet the exhaust was. I drove straight back and them and he tuned it for "added pop/crackle", dang thing sounded like it was constantly backfiring! Told them it was too much and I just wanted the stock tables put back. Now it's perfect. GM really must've spent a lot of time to tune the exhaust sound to get it so perfect.
Crazy how much the tune can effect the exhaust sound.
