Appreciate all the comments. I went ahead and uploaded the stock high octane timing tables and took it for a drive this evening. Successfully achieved 0* KR throughout my WOT pulls. With that, I will probably add a degree or two, and do the same thing. I may also leave the stock high octane timing table alone and add a smaller pulley and see what that gets me. @ WOT, I am currently between 11 and 13* of advance, so nothing crazy, but that was the stock table so can't be too bad I guess?
I am thinking it will handle 14* of WOT timing just fine. We'll see how it does over the next few days!
Either way, I was seeing up to 9.6* of KR before E85 on the stock timing tables, and now I am seeing 0* on the stock timing tables. So that right there was worth the fuel switch in my limited opinion
