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

I am going to be going with a flex fuel tune from Dusterhoff eventually.
In preparation I went with FiC 1200 injectors.
I am looking into a dual pump system as the bap was not recommended.
I am going to use the ATI 10% lower pulley.
Is he the only one that offers flex tunes? Does he have a website?
Looking at Tim Barth performance packages. Either the 800hp or 900 hp package. Seems the 800hp+ with E85 options might be the best bang for the buck but I notice when you select the E85 parts option it doesn't list what they are. Ends up being a little over 6k and states you can get 850hp....2k less than their 900hp option.

Anyone with experience with these packages?

One big downfall is I don't see any flextune options which would make it suck if I got caught not being able to fill up with E85 anywhere. Risking the engine at that point.

Give SRT Autoworks a peek. They churn out these packages left and right. I don't have social media but I think they have a pretty active Instagram page if you want to see some of their work.

I have the package on my car and love it. I would however really like a flex tune one day. I run my car mostly on the e54 tune since e85 isn't always e85 around here. The station close to me is only 54 and the 85 station (that has tested quite a bit lower a few times) is about 25 minutes away. Wife isn't fond of having drums in the garage filled with e85 so im stuck. lol
My car made 939 to the wheels on e85 with an IAT of 140 degrees... got to love Arizona August dyno pulls. haha
Other than not having a flex tune the car is perfect. It drives better than stock and it was my daily last summer. Im planning on ported snout, TB and a killer chiller package but honestly the car is so nasty on the street right now I cant imagine more. My car did a 5.49 60-130 on the e54 tune and it has more in it. I think you'd be a happy camper for sure.
Interesting. I have a station 2 blocks from my house that is full E85 in the summer but dips to E75 winter...but I don't drive it in the winter. lol So did Tim Barth give you two tunes? One for E85 and one for E54? Kind of a custom E54 tune? Any extra cost in that?

Also which package exactly do you have? Parts list and price would be awesome. Feel free to PM me.

My only main concern is longer trips where E85 might be hard to find in Northern MN. Overall I could live without a flex tune though. We have other cars we can take on long trips but sometimes it's nice to take the Hellcat. lol
Was thinking Barth but after looking at Dusterhoff the price of the top stage 4 package is pretty damn appealing and quite frankly way cheaper. On top of that it's a flex tune. Hmmmm
