GT350 on E85/headers question

[Klaus]

Who is running NA GT350 on E85? What gains did you see? What fuel system upgrades did you do? Are you running headers?

I have seen guys running stock injectors and claim that they are fine. I have also heard that the GT350 ECU will bump timing if you run E and that it is not necessary to tune.

Finally, is it worth doing headers on these? I recall reading that the stock set up was pretty bad ass and flowed very well.

Help a brother out.

I can answer one question for you! You CAN NOT just put E85 in your GT350 and expect the stock tune to adjust for it. Not gonna happen and you’ll damage the engine in the process. You absolutely have to be tuned for E85 if you’re gonna use it.

We can't stress this enough. My tune wasn't what it should have been and burnt a hole in #2.
