I tried it a couple times when I bought my 16 four years ago. I didn't care too much for it. I suppose in time you could dial it in with trial and error with rpm but you can do that your self like poster above said. I don't track my car just play around, But why not try it and see what you think? As for why I didn't like it I guess there was no feel and you just get what you get. I should try it again now that I've got a lot more feel for the car.
