You should roll with it for a while and see how you feel about the performance. If it's gear hunting or having frequent downshifts you should start investigating what gears make the most sense.

Or were just pointing out the importance of not going lower?

was gonna get one of these today at the 4x4 shop while getting my new 33's. the owner said not to even waste my money and that they dont do very much of anything. he said it's cheaper just to go to the dealer to get them to recalibrate the computer for larger tires as it's only 80$ to do it there opposed to 300$ for the superchip. he said they're pretty much useless on gas engines
he's the owner and I would assume he'd want to make a sale so I trusted he was being honest.

The important thing is not going lower than the Tune. For instance you don't want to run the 91 tune on 87 Octane fuel.

It certainly wouldn't hurt anything but there wouldn't be much benefit. As infrequently as you'd bump up against the knock sensors using the prescribed octane, you run into them even less with a bump in octane. If you have changed some sort of mechanicals such as a throttle body (not just a spacer) or added headers there could be a benefit as well.

Let me pick your brains just a tad more.
I have K&N drop-in filter and Flowmaster muffler, but this morning just ran 87 tune for stock engine (3.8)
Should I bother with Advanced tune or add-ons that I have aren't significant enough?

Neither of those items will change things dramatically enough to effect the tunes. Headers can as they cause better cylinder evacuation and a throttle body will let more air in at lower throttle position percentages without having the tables changed to accommodate the larger bore.
