I had a flex fuel vehicle once. In order to put a supercharger on it, I only needed a special program and a supercharger. However, if it wasn't flex fuel, you would need injectors. Why? Because FF has bigger injectors to make up for the lack of power. FF also has a sensor in the tank to detect E85 and then it can advance the timing and pulse width.

I sure as hell don't know the intricacies, but do you think with our Caravan it's a simple as just pumping E85 into it? (Not that I'd want to.) I was surprised to see that logo inside the gas door. Is there something different about the GM engines that required more engineering in order to put the fancy FF badges on?
