Default Misfire Cylinder 1

I know there is tons of posts about this, but I want to see if I am missing something.

16 sti, blouch turbo dominator, tomei headers, cobb downpipe, short ram, invidia n1 exhaust, 1000cc injectors, aem fuel pump, fuel rails, flex fuel set up, process west FMIC.

I am now throwing a misfire cylinder 1 on e85. I swapped all spark plugs, gapped down more, swapped coilpacks, stayed misfire cyl 1, replaced coilpack, still throwing it, did a compression test, was good, swapped injectors positions, still misfire 1, pulled the injector while running to see if it would run rougher or the same, ran rougher, which tells me its not a true miss. Did a wet compression test with scope, all good.

Is there anything else I am missing, or is it tune related?I did give the data logs and tune over to Cobb, but in the mean time seeing if I missed any other parts to check. I did put 93 back in and still misfiring so its not a bad batch of gas.
