I think in passing situations, I would actually like a quicker downshift. I find my stage to be laggy in passing situations (not big turbo laggy mind you). You can definitely feel a noticeable delay at say 50mph when passing before the large turbo spools fully and the engine is making maximum hp power. Helpful when squirting through traffic. Or maybe I'm just getting too used to my X5Ms insta spool engine.
