E-85 vs meth injectors/pump
There are 93 octane cars not getting 120mi per half tank. I think this mileage is far fetched on ethanol.
Ok.
Depending on what type of driving, it will indeed get 120 per half. The average is 100-110, but I'll let my car know you think it's incorrect.
Either way true mileage isn't judged by "half a tank" anyway as again, we all know the second half goes much quicker.
My personal best so far is approx 240 on a tank, so about 17-18mpg, only about 2-3 less than I would get on 91. When I have some fun with the car all the time it gets closer to 200-210, which is 100% fine with me for a a evo with 400whp+ true mustang dyno output. Also, the larger turbos are a bit easier to get better mileage as they won't spool when you sneeze like the stock and variants can. 
As far as that 'mileage' on 93, I'm sorry to hear that depressingly low 'mileage'. Maybe 91 is better in some regards.

The availability of e85 was the determining factor in my decision to run meth. When I take my car to the hill country or ozarks, I still want to run high boost, therefore, I just take a jug of meth with me and I'm good to go.
So I was at close to half a tank tonight on E85 (I run it 24/7) and decided to snap a photo.
It's a bit over half tank so still some miles to go till "half a tank". This was more city driving than I usually do a week and bit of "having fun" as well.
Some more fwy like I usually do and less fun and you can see 120 is no issue. I'll take a photo end of this week too to see if it's closer to that "crazy 120" number.

Methanol is a cheaper bet it seems and if you can invest in a quality kit, it appears to be the most effective.

We are also logging the miles on our most recent tank of E75.
I have the same injector and turbo combo as Bryan on my IX and we are both cammed. I am getting close to the same results as Bryan. I suspect I maybe having a bit more "fun" then him though. Full time E-85 vehicle
I have E85 mileage data from over a year of running it 24/7. This is normal average mileage when done correctly.
On almost 100% fwy it's not much worse than pump gas, this might blow your mind even more.

I have gotten 250 miles per tank of E85 with no closed loop modifications at all.. pte 880's I average about 200 miles per tank with mixed driving.
IMHO the best bet is to run meth AND e-85

I've seen the smaller injectors perform with much better mileage than the larger ones.
On the 1050's we used to run the mileage was closer to stockish.
The move to the 1650cc's seems to be less efficient, maybe a more course spray pattern and having a hard time running really low IDC's.
