Higher octane only really matters when you are boosted.
I've had 500+ hp boosted vehicles. I ran race gas (110) when I wanted to turn up the boost.
Detonation, detonation, detonation. The only reason you would want/need to run higher octane.
Normally aspirated engines don't really need high octane fuel unless the compression is high.
When tuned you shouldn't need high octane either. Unless, their approach is to advance timing etc.
Don't know much about tuning our trucks. I do know, however, it is usually a waste of time getting a tune unless you are going forced induction.
Tuners will turn up boost, advance timing until detonation, then usually dial it back.
