u need to be a good river in order to rev tht vario, basically when u put it in S mode what it does is it takes RPMS to the peak power point, and waits for the gearing to play and bring the engine there. once the engine is there it'll give tough time to many cars whom ppl think are untouchable like SE and vti, i tried it myself against frnds prosmatec, vti being vti, was winner!
