MAP 3 : E85

[StingerT303]

I love the JB4. Map 2 is awesome. Pulls VERY strong. I'm at altitude in CO, so the best fuel I can find is 91 but have not had any issues on Map 2 so far.

I want to try Map 3 out. Do I just mix E85 in the tank at an estimated 30% of E85 to Unleaded? Do I need to change the fuel pump or anything else?

Maybe it is more simple than I think but just want to be sure.

It's as simple as you described. Just add E85 to make it ~30% of your tank and you'll be good to switch maps

5 gallons of e85 and the rest 91 is what I use for my car
