You CAN run E85 without FlexFuel, but its not called FlexFuel, its just called running E85. Its a separate tune, sort of like you would use for high octane race gas.
As for running stock injectors with E85, never tried it. But arent stock injectors like 310cc? Anyone know? If so, that is too small for E85.

If the math is done here it comes to be a minimum of 384cc/or 37 lb fuel injectors. When running E85 with the stock fuel injectors a DTC will appear as not enough fuel volume will be available to use because the stock fuel injector size is too small to run E85. You will need 550cc or larger fuel injectors and upgrading to a larger fuel pump is cheap insurance as I have seen several people have their stock fuel pumps fail after upgrading their fuel injectors,running E85,and not upgrading their fuel pump at the same time.
