I have a 2020 3.5eb and loaded a 93 performance/tow tune. My OAR would sit around -0.26. And would see +4.00KR on light acceleration. Thinking maybe Covid fuel is crap I put the 85+ Adaptive octane tune in when I accelerate the truck now goes -6.00KR under acceleration and my OAR jumped to +1.00 and my trucks a complete dog. I’m lost at this point. This is all on shell 93

 

Have you done any logs and sent them to 5 star? That’s where I would start.

 

I did a short log and changed to my 93performance tune and my numbers were perfect

 

Maybe they sent you my 94 octane tune lol. It expects true 94 octane, but runs HARD.
Can't compare to an 85+ octane tune.....it's just a tune with a more tolerant and weaker load command and less base timing across the board. That said, I am speaking from experience with the BCB tune I had that was "adaptive" and it made stock or less horsepower on 94 octane.
