E-85 on a stock 370z?

JeffP-Z

I have done some searches and have not come up with a concrete answer yet so here goes....Can you run E-85 in a 2010 370z? I have added Stillen Gen 3 CAI and ARK DT-S exhaust. It was originally tuned on 93 octane. Can I switch over to E-85 safely? Do I need an E-85 sensor kit? I was thinking of switching to E-85 if possible and having it retuned as I am about to add Berk Resonated Test Pipes. I read the owner's manual and it specifically says not to use E-85 but I wanted to ask people with more experience here who have already done this. Thanks in advance and apologies if I missed the answer in the existing E-85 threads.
