Is anyone running e85 ? If you are what exactly do you need to run e85?

I know you need a tune specific for e85 I believe, not sure if you need any hardware like different fuel injectors. I'm more curious if anyone had big gains switching to e85 or if it's not worth it.

E30 & E85 is regarded highly around here and no doubt it makes more power. However the tricky part is availability and knowing the stock you're getting is actually "E85" consistently. One moment you could be getting E85+ and then another day you could be getting something much lower in octane (yes, this happens with non ethanol gas too but it is still more consistent overall and not as bad of drop in octane due to less regulation for E85). Then you have to factor availability, if it's not available in the next town and you don't have your flasher you are sold out of luck. IMHO the gains are not worth it for me on a daily driver and once you factor in availability, consistency, and the fact that it burns off much quicker than 93 I'll stick to 93 or actual 100 oct (if I had to go that far despite price). It's a sham to me and why I never hopped on the bandwagon. If you know you have good stock and availability isn't a concern then it does make great power in exchange of burning off faster. If you're going to go this route it would be better to do one or the other vs going a "hybrid/mixture" tune that is adding more complexity in the long run and a higher risk for knock if the fuel mixture is off.

Doesn't E85 require different injectors and fuel rails? I don't get why Ford didn't make the Mustang a flex fuel vehicle. E85 is all over around me, I would use it.

I believe so according to this: http://www.mustang6g.com/forums/showthread.php?t=68987

You only need a new tune. Fuel injectors are not needed but will benefit the tune. My friend has a 2013 3.7 and has been running e85 on stock injectors for about 4 months with no issues

I'm also interested in this, I don't see MPT offering E85 but Lund Racing does for 11-14 which should technically work for us

Lund would probably who you would want to go with for the E85 route. The 5.0 community loves them when it comes to corn.
