Is it practical to tune an ej20k with just an apexi neo afc for e85? I can't find an absolute answer.I'm not trying to get big numbers or anything like that. I just want my car to run better. It runs like shit on 91. Would I really need a standalone and 1000cc injectors? I don't feel like paying 7 dollars a gallon for 100 octane either. But if its not then 100 octane it is....
