ok... I am never going to put E85 in my ride. However, like many of you out there, my engine is programed to accept this E85 crap. Does this make the car run less efficient on regular 87? If so, what can I do to ammend this rediculous factory setting?

I'm intersted too. I'd also like to know if programmers like Hypertech ect. make it to where your FF motor is no longer E85 compatible. I'll never put E85 in my truck either here in South Carolina so I wouldn't mine a good tune for 87.
