I’ve got a twin turbo 5.3 with t56 swapped in a bmw with a 6106 pcm on HPtuners Pro. I own that software but haven’t really done anything with it yet, it came with this car I bought.

i am making around 600hp on 93, need more power for fun, but want to be able to run 93 also whenever I can’t get e85 locally. I don’t know what I need to do this. I have searched on this forum and found some stuff about how to wire the flex fuel setup in but I don’t know if I even have a pcm that can do what I need. Do I set it up for flex fuel with a sensor and wire that in or do I just have my tuner tune two separate tunes (one one For 93 and one for e85) and switch tunes from laptop when I’m at the gas station? Sorry for my ignorance. I need advice.

nice looking set up.

i know the p59 computer can do flex fuel , dbc, and 3 bar speed density. I used one to 1000+ wheel hp

search for the p59 flex fuel thread in this section. It takes a bit to set it up but once it's working It's pretty great.

This thread here may answer some of your questions, hopefully. I was considering going this route, but I haven't had the chance yet.
