Need E85 advice please

im in the same boat and running a 3.1 on a fresh E85 tune for the first time this weekend. I have seen 20* of timing with 0kr on the 3.1 so far in the last few days street tuning but I have a small cam so idk how comparable it is. If I blow it up racing this weekend I will let you know

That would suck... But I appreciate it

Well I made about 25 passes with it this weekend on the stock pump, 3.1 pulley and 19.5* never blew up and I logged every pass it never leaned out or had any KR. I would say a 3.1 for sure and probably a 3.0 would be safe with stock timing with the stock cam on E85
