Thinking about going to e85

Right now I have my car set up with
Zzp fmic
Zzp downpipe
Injen cai
Injen charge pipe
Zzp dyno tune @23.7psi
The car made 307whp and 332fpt
My question, is it worth it going to e85 and what other mods will I need to support it

You'll hear different opinions from different members, but E47 is the way to go. It is kind of a pain, though. Not that the mixing is a pain, but for a daily driver going out of town, you have to plan your route around E85 gas stations (which you'll have to do even with running E85.) I had E47 for about a year and it is amazing the difference it makes in power, but I got tired of the work involved with running it. The power comes from being able to turn up the timing to around 23 degrees with no knock.
