I've seen kits online for retrofitting your vehicle to make it flex fuel. It looks like most of them are just a computer that will adjust your fuel trims. It seems to me that there would be more you would have to do to your vehicle in order to safely run E-85 long term. Has anybody had any experience with these kits? Side note my work van is FFV and I run E-85 in it most of the time. Fuel mileage isn't as good but it runs so much better and with a noticeable power increase. Granted it has the 6.0 so there is already power to build on. I know the 4.2 wouldn't have as big of an increase but I still like the idea of running E-85. Any input is appreciated.
