I just met a guy with a race chip on his m8gc. Said same thing doesn’t feel any faster.
Flashes 100% do not work on 21s... I’ve spoken to over a dozen tuners from Noelle to Active Autowerks. It’s more then just a software issue, it’s also a hardware issue apparently.
Can anyone confirm full JB4 with EWG connectors worked for them on their new 2021 s63-tu engine equipped beauty?
Happy thanksgiving!!!
