Both piggies are capable of running up to a 50% E85 mixture without any type of reflash or extra flex-fuel kit, it's recommended, but not required. Anything beyond that get's sketchy with fuel trims without some form of flash or ignition advance to take advantage of the extra power E85 can make. I've ran E60-E70 before but never sustained it for more than 100miles w/o a flash, but my LPFP/HPFP are healthy as can be.

Sorry if this thread got confusing for you from the amount of propaganda from inexperienced users going on in this thread.
