Quick Question
 

If I run a 93 oct tune and I put 98 oct in my car will it hurt it or will it just run better? And one more question if I do a e85 tune and I put 93 oct will it harm the car.

As for the first question it shouldn't hurt anything. Second question is yes….if it even runs.

Then ill stray away from e85 since the closest station is like 25 miles away. Thank you

The first one depends on how aggressive your valve timing is. If you are really pushing the edge, running fuel with a significantly slower burn rate could result in burning fuel being forced past an open valve that would have been closed in time for a faster burning fuel.
The odds of your tune being that finely done for 93 are slim though. Mostly you'd just be wasting money on the more expensive gas.

How far out of your way is that station though? I'm in the same boat, and I ONLY run E85, but that station is on my way to the rest of civilization so it's really not inconvenient. Not as easy as pump fuel 5 miles from my house, but it's not like I'm going 20 miles out of my way.

Depending on what you use to tune, you'd give yourself a pump map and a mixed map or two, or just flex fuel. I have 2 pump maps (all 93, and 50/50 mix) just in case I get caught out somewhere, but luckily I've never had to use either yet.

I can run e85 on stock injectors?

From my limited knowledge. Yes you can and many people do. However, when you introduce e85 into a boosted engine you start to demand of your car more power and greater fuel needs than your stock injectors can handle. Many boosted cars running pump gas don't get to this point which is why their is not a need to change the injectors.

Yes. But where you are at power-wise now, you should not. You'd have to turn your boost down to run E85 at this point. Until you upgrade your pump and injectors, don't change a thing: leave your boost alone and stick with 93 octane.

I was responding to your thought of avoiding E85 because of its availability in your area. If you have no desire to upgrade your fuel system, yes, ignore E85.
