Time to mod finally...going E85 and need advice!

Hey all,

I know this has probably been discussed hundreds of times...tried the search function and didn't find a good summary of info on it.

So I want to convert to E85 with full supporting mods but maintain a safe reserved tune. Don't want to be blowing anything up.

I don't really have a HP goal in mind...just convert to E85 and see where I end up.

So with that said here are some questions.

I'll probably go to Tim Barth for tuning, seems he's the most reliable person out there for remote and safe tunes and the most popular for a reason. Or am I wrong on that?

Parts list:
What pulley will I need? Suggestions?
Bigger injectors of course. What will I need?
Boost a pump or dual fuel pump setup?
Cracked PCM of course for tuning. Best source for that? I'll also need a hand held or mounted tuning device obviously, best one out there?

I think that covers it for parts? Pulley/PCM/Tune/tuning device/Injectors/Fuel Pump

Am I missing anything?

And finally I'd LOVE to have a flex fuel tune. I read a while back tuners where working on that but not sure if one's available or functional yet or not? In the event I can't find E85 anywhere it'd be nice to run it super low and fill up on premium and have the PCM do the rest of the work. Ran into this issue on my last car...Dad was driving it and couldn't find E85 so filled up on premium gas...shortly after the rod went through the engine block and out of the oil pan....ugh. lol Of course the hand held Diablo tuner was in the trunk and could have flashed the premium gas tune to it beforehand but he didn't know. lol

E85 isn't really hard to find. It's just low quality, poorly regulated gas. So, be sure to buy a test kit and test it every single time before you fill it up. E85 in and of itself can be irregular, but it's more often how the station stores it and if the tanks leak or are sealed properly. E85 draws moisture out of the air and causes water to condense in the gas station fuel tank (or your gas tank if it's left for more than a few days undrained). So, you have to watch out for water deposits and E85 concentration. The two stations near me that have it, I'd never use it in any of my cars (grocery getter or otherwise). They never test consistently and one of them routinely has to shut down the pump at least 2x per month for maintenance to remove the water buildup.

In my high performance cars that were E85 converted, I only ever ordered drums from racing suppliers after I blew 2 sets of plugs in a week due to bad E85 that I got AT THE RACE TRACK.
