87 octane tune
I know this question may seem pointless but I think it's necessary in our world of rising gas prices. What kind of rwhp/rwtq can a bolt-on (CAI, headers, catback) 5.3 get with an "aggressive" 87 octane tune? Is it even possible to create an "aggressive" 87 tune with no hint of KR or detonation? Any info would be appreciated.

You also get the benefit of the better additives with premium.

That's why PCM's have high and low octane tables. Tune your high octane table to 93 and your low octane table to 87. I don't know the exact details, but the PCM should take care of the rest.
