Is anyone running the DiabloSport "generic" tuner in their Sport? http://www.diablosport.com/intune-i2/intune-i2-performance-programmer-ford-vehicles/ Any thoughts? How fast are tune loads? Are the tunes separate for performance vs mileage? Or is it a single tune to improve both? Main thing is I read reviews about early on it having some tune issues, but not many updates since then. At the time I don't think it supported Explorers.
