I was looking into running E85 and I can’t locate specific information about a particular question. Seeing to run 25PSI I should run around 1000cc injectors, should I burn a chip that illustrates that there are 1000cc injectors or should I use the equivelant of 660cc for pump gas, seeing the difference between the two fuels. I know my O2 sensor would read it as if it were gasoline (same with a wideband 8.05:1 E85 = 12:1 Gasoline). I am leaning toward writing a code that uses 660cc. Any knowledge would help.

i don’t know much about tuning at all, but you do know that you need to use stainless steel lines, tank, fuel pump, injectors, etc with ethanol?

Not neccessarily, methanol you need all stainless E85 will be alright in conventional setups.

Correct, you tune for the smaller (corrected) number.
