I'm not sure I understand. You mean it should release both throttle and brake at the same time? Or by "feather" do you mean "push"? If so, what are those situations? The only one I can think of is deliberate rubber burning... Edit: I guess another is for not spooling down the turbo when braking for a corner. If you're worried about that, you are probably far from a normal street driving situation.
