Powerchip after a few thousand miles
Im guessing its either that the adaptive ecu has gone back to its lazy ways & I need to drive the car hard again to see the update again, or I just got used to the extra punch. I think it may be the adaptive ecu because the car seems lazier than it did when I just got the ecu update done.




it's not until i get into a C300 loaner car and I realize there is a pretty big difference.
