We flashed an FG F6 310 tune into my BA XR6 NA, I now got a 6 speed auto, LSD and boost all with a flash tune and it works honest, we did it ourselves coz no one at Ford actually knows what there on about, I found even tuners don't know sh*t and us back yarders know heaps more. Oh and the other day I polished my Volksie and it turned into a Ferrari but we burnt it down to the ground coz we hate Ferrari's.
