Follow along with PK as he explains what the Flex Predator from DiabloSport does. (Hint)It is a tuner that allows your non-Flex Fuel truck or SUV to run on E85 Flex Fuel. And, it still will tune and optimize your truck or SUV for mileage or performance gains just like the standard Predator tuner. It’s a win/win combo.
