That's a lot of ethanol! Is it safe to run that high even on flex fuel?
With the flexfuel kit it's safe to run all the way up to 100%, just depends on whether or not your stock lpfp can handle it, when you upgrade the lpfp, 100% is a walk in the park for the car, no issues or hiccups, at least for me
