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

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.

I'm in Southern Arizona, I stumbled across SRT Autoworks after picking up my Challenger. Seems like you're satisfied with all their work, how long ago did they do your car?
Yeah man I’m beyond happy with it. Bought the car brand new at the end of June in 2019, had it in their shop August 2019. Didn’t stay stock for very long. I’ve had zero problems with it. It’s got about 9000 miles on it now, package was put on at around 1000 miles. Go to the shop and talk to Tommy, have him give you a ride in his car and you’ll be sold.
