I feel like someone is trying to punk you or this is sarcasm, I'm not able to tell.
But no, bmw will not physically see anything. But if they looked deep enough into the ecu even if you flashed back to stock they will see boost levels and a lot of other variables outside of stock. But it's typically only if a puma case is opened. |
Are you talking about what I am saying or what he is saying? I am absolutely positive almost every flash tune cracks open the ecu to flash...
