Does anyone use a Lund Flex Fuel tune? How has your experience been? I run ethanol on my Saleen and in the last terminator I had, there is 4 stations around town with year around E85. However once I leave town it’s 2-3hrs before I can find ethanol again. At this time I’m thinking about intake, exhaust, smaller pulley, injectors, fuel rail. If needed I’ll do a return style fuel system. So I’d like to run ethanol to make the most of it.
