E-85 has less energy than normal fuel, which is why on an E-85 tune you have to run huge injectors and tons of fuel, but it does have an extremely high resistance to detonation/knock so you can run more boost, more timing as long as you dump in enough fuel. Running E-85 with normal fuel would actually be a downgrade, yes your "octane" would go up, but you are getting less energy out of the mix. It would be more ideal to run a water/meth kit, that way you are adding more chemicals in addition to your normal fuel. But in short, don't add E-85 to your fuel
