Has anyone given the Dinan transmission software a try on their 540i? I have an auto 540 :( and my car has a tendency to lug itself in 5th gear alot and I find myself using the manual select mode (4 3 2) alot to get in the right gear and the shifts are super slow.. just wondering if this is a good way to improve these qualities. Of course I know the real fix would be to get a 6 speed manual but that isn't an option. Anyone have any opinions? Thanks!
