You must understand that any chance of improvement will have to come with very vehicle specific VG tabs and installation instructions (and data to document the testing of the tabs on a previous particular vehicle configuration). And even then it sounds like the gains of VG on a car are on the slim side (i.e. .006 CD with a whole lot of tuning I'm sure). I do not find such a large effort for a small (if any) gain very appealing myself Maybe I'm wrong.
