    Flex fuel is not a good idea on boosted applications since the alcohol % is inferred. So a separate dedicated e85 tune or a 93 would be best for it

    File attached. Like Bill mentioned above, you do NOT want to do a Flex Fuel tune.

    Actually FLEX works fine under boost, tested on my car and trust me had LOAD over 3 there...but you need to have everything
    else on point...otherwise TRIMS might just go to the moon leaving you running 13.0 AFR at WOT and melting your pistons...
