RaceChip for 6 Series
Looking to buy the RaceChip GTS Black for my 2016 640i Gran Coupe. N55 engine.
Anyone have any experience of using RaceChip with their 6 series ? Also the claimed mpg increase of 20% probably is not realistic at all but I guess if it can help the mpg in any way then better than nothing....as the 640i petrol is just so inefficient compared to the more common 640d lol. And yes I know its not a proper tune and all a piggyback thing but the idea of a plug n play stage/tune and being able to switch back to stock anytime with the control of an app is more appealing. Each to their own I guess. |
