Tune first, running E85 on an non-e85 map will cause the car to run lean

You should not run an e50 mix in your car unless you have :

1) stage 2 LPFP
2) e50 tune
3) used a proper amount of an E85 fuel treatment, upon fill up. Lucas makes one, and you can get it at Autozone or almost any automotive parts store

Yes

Also, don't run 2-3 tanks in a row of e50.

Once your tank is empty, fill up with e93 and run a normal tank of gas through the system

It's really not a big deal to run far more than 2-3 tanks of e50 in a row. I haven't had a pump gas tune on my car for years.

My buddy has a e36 running full E , and i remember his car he said he couldn't let the e85 sit for long in his tank , I guess he had to take out all the E and refuel it , i'm not sure how long it sat .... but my question is , has there been a problem with yours if you ever had it sit , or if you have an idea of what im talking about lmao

Not necessary.

Pump every once in a while is nice. But this is excessive.

On e50 with e60-65 in the tank I literally fill up 3 times a week driving to work. Doing this would be annoying as fuck

I run full E85 just because I got tired of mixing plus a little extra safety.

My normal station regularly pulls down e92-e95 when tested so I don't have the confidence to go full tank with my mostly stock system.

Thats a strong mix !

Mine , every time I tested, has been actual E85 so I try and fill up only at that location but I have the fuel system for it.

Nah, injectors don't like it if it sits too long, anecdotally speaking anyway, but I haven't had any issues. Throw some injector cleaner or E85 additive in if you feel like it and don't worry about it. Been running ethanol since 2012ish. Replaced injectors twice. Might have a couple months of pump gas use in there.
