Yep that would be great if they would, but for whatever reason they're sticking with stage 1 tune. I frankly see no point to have 8 dial settings when they don't recommend you ever change from the default level 6 setting unless you use race gas. Seems so simple, yet I'm not an engineer and I don't work for them, so we essentially have 2 options JB4 or custom tune. Custom tune is irreversible and all E85 isn't E85, by me the pump says could be as low as E60, so you really need an adaptable tune to run it, like what appears to be Map 5 on JB4. I suppose the custom tune would be ok if the mix was really using E85 all the time, but just wouldn't be optimal.

Not changing until Spring, so maybe something better is out at that point.
