I know there are guys that habe run e85 in the 3.5eb non-flex fuel with no issue. Are there supporting mods needed to get an E85 performance tune? Also, I have an sct 4 from 5startuning.com.... has anyone gotten an e85 performance tune from them?

 

What does 5Star say about that? I'm thinking it may need some fuel system mods and wider band O2 sensors?

I KNOW if you try to run E85 in it, your warranty is gone.

 

Haven't heard from them yet. As for my warranty idgaf because my buddy is a tech and I get parts for cost and his labor rate is heineken .

 

I know most vehicles need a bigger fuel pump, I know livernois has one they sell. E85 can be a lot of fun when properly set up. My old supercharged 95 mustang loved the stuff. I did have to put in bigger injectors and a higher rated fuel pump.
