Ive posted my data logs somewhere around here. I eventually pulled so much ignition timing out some places on the map, it was equivalent to stock.
Our engines definitely like higher octane, especially in hot conditions and under extended high rpm use.
I'm looking forward to trying e85 with its 108 octane rating.

E85 is definitely nice. Worth having to carry fuel jugs around.
I still wont track in the summer. Afraid of what will happen lol
