I just tested the local e85 pumps and found one with e83, so going to switch over after this weekend and start with my tuning for it. Just curious what to do with the timing tables when switching over. Should I give it more timing everywhere or just in the wot areas? and how much timing is too much for my setup(stock longblock, 2.8kb, estimating 21-22lbs). I'm at 16 degrees now on 93 @ 19lbs. Was planning on just 18-19 degrees but if more is plenty safe I may push it a little further.
