So I've done the swap to E85 with my 347cc Blue injectors and I am amazed at the difference. The first tank had gas left in it and that didn't go so well but once I got the mix to the full 85% the difference is night and day. I went from 18PSI on 93 octane pump gas to 10-12PSI on E85 and I'm making noticeably more power. I started with my injector size of 347cc and multiplied that by .670 to get the "injector size" that adds the necessary fuel for straight E85. The formula I used in TunerPro to change the constant is 315/(actual injector size*.670). It's a very close estimation to start with. You can adjust for a custom ratio based on the info I found here. I actually used a very aggressive timing map, that was posted by, I believe, TMM9 on a different discussion, with no knock once all the 93 was run out of the system. In fact, I don't think this car has ever pulled this hard before, it's absolutely phenomenal. Once I get my 609cc injectors in and on the car, I'll retune and crank the boost again, then break out the camera and get a clip of the awesomeness that ensues. If you make the change and need places to fuel up in the US, try this site. Lots and lots of places around.
