Easy as can be right out of the box. I even used a Mac and had no issues updating the device. Simply plug it into your vehicle after updating, pick your desired tune, let it do its thing, and done. Installing tune took less than 10 mins total. Capped off with the Diablo Sport OBDII cover. I plan to have a custom tune written by DiabLew once I'm done installing different exhaust components to maximize everything's potential.
