Mike, tonight is cool, it never gets really hot where I live at all. I mixed in 100 octane fuel it felt better

The shop I go to to do tuning Autohaus Frankfurt is a Dinan dealer. He spoke to them and indicated 1 month...When I called two months ago they said February so we'll see i guess. Probably around same time BMWUSA updated their configurator to include M4...
