You won't regret it trust me!! Start off with 4-6G of e85 and go from there. Lots of fun. Oh and don't forget to run it hard a few times in 3rd gear.

So in order to run a mix with e85, I would need a flex fuel line? Or can I just do jb4 and 30% mix of e85 plus 93? Sorry I've been searching and can't tell what's needed. I have an e85 station less than a mile away so I want to take advantage!

Just get the wires. They're 30 shipped and take 30 minutes to install if you don't take off those chassis braces. Otherwise 10 minutes tops.

Just installed my wires today. It was pretty easy install. I put 5.5 gal of E85, and the rest 93. I took a few pulls so it could learn, and I was fairly impressed after that. It was not an enormous difference, but a good difference nonetheless. Definitely pulls harder.
Thanks for all the inputs!!

No you don't need wires to mix under 50% e85 with a proper setup (map 5 jb4). According to burger tuning, simply mix 4-6 gal of 85 with 93 and set the jb4 to map 5.
I heard if you want to add significant power you can convert the car to run on full e85. The shop that installed my jb4 and FBO said that there is an engine management kit that replaces the fuel pump and comes with a sensor plus a few other things. Its supposed to adjust timing to compensate for higher ethanol levels. The kit safely allows running 100% e85 but before I spend the money on this- is there anyone else out here with this kind set up on the jb4?? Thanks

Burger tuning don't have stage 2 anymore on their site (N55). New is just JB4 but bigger box. What is going on with this?

I believe for the n55 the standard offering is just the stage 2
