Simple question... would adding acetone to the fuel require tuning to a higher octane program? IE. would adding 6oz of acetone to 25 gallons of 87 octane require a bump to a 91 perf. tune or somehow require a different alteration in the gryphon programming?

I think "debacle' is probably the correct word here, but I suspect you may have meant "debate".

I honestly don't think acetone is going to do anything one way or another. I've certainly read the "add acetone" articles that say it will boost your mileage and I even tried it (since I know acetone is flammable and didn't see how such a small amount could really hurt anything). In my case, it did not change my fuel economy at all, so I stopped using it.

I doubt you'd be able to use a higher octane program with acetone. I'm pretty sure it is more volatile than gasoline so if anything, I'd think it might LOWER the octane rating of the mixture. But, even if I'm wrong on this, the percentage cannot significantly change the octane rating anyway. Your 6 oz per 25 gal mixture is 6/3200 = 0.19% acetone (less than 2 tenths of a percent) - so I can't imagine it has much effect at all.

About the only REAL effect of adding acetone is if you happen to spill some on your truck's paint. It's an excellent paint remover/finish destroyer! (No, I didn't spill any).
