I can notice the difference definitely but Like some of you I wasn't big fan of the 'virtual' update vs some physical tune.
Apparently this chip update is processed via a Bluetooth update/uploaded to of the car software , which unlocks more power… and is warranty safe on BMW side.
Now give me more tips on the right questions I should ask to this dealer so I can do a proper verification (have I been screwed or not 🤪  |
Given I have a M850i as well and looking to mod early next year the website referred to is piggy back mods/chips (granted translated to English) so nearly no different than any other solution on the market. Do you have any more details? A road trip to Quebec is not out of my parameters so hence trying to understand if their offering is anything better than a Racechip, etc. piggyback or just some OEM'd version they offer but at the end of the day same outcome.
