I was getting crazy detonation with no other mods on the 93 tune, until I got a custom tune.
I ran like 10 passes with 93 octane fuel and on 91 performance tune. Times were worse than my stock tune. Only getting knock at around 70 full throttle only a 1 on knock retard nothing higher yet. But my best run wad 5.85 tuned ane 5.76 not tuned. I believe there 1 to 2 shift hangs abit. Causing slower times.
