Im running COBB stage 2+FMIC aggressive with 93 octane. Ive been seeing people using a mixture of e85 and 93 octane. I was thinking about giving it a try since I found a semi local place in philly that sells e85. But will it benefit me or be worse for my car? Do I need a race gas map or something like that to use e85? Just looking for some info on this. THanks everyone.

the couple of times I've done it on Cobb just to test, I get fuel mixture codes and car runs a bit lean. You won't get anything from it unless they come out with a e85 map, or ATR and then you can get someone to tune for it.

Thanks for the info. I was thinking it probably wouldnt run so great. But thought it was worth asking. I was thinking of getting a custom tune but not sure if I want to mod anymore yet. And as far as the e85 I dont think I want to drive into center city every time I need to fill with e85. So not sure what to do yet.
