Hi Guys, Porsche gave the software upgrade which actually decreased the miles I was getting 250-270 estimated range now will not go above 170 (driving very cautiously heating on low as can go for as little time as possible) will this start to creep up again as Porsche has assured me it is perfectly normal and will learn the driving style in thenext weeks/months and increase but I do not believe this as I am getting 1.7-1.9 kwh per mile and this is real-time.
