For every car that comes into the dealer -- they are installing new ECU software that prevents ECU tuning. So if your car went back to the dealer any time during the last 3-4 weeks, there's a very good chance it got flashed back to stock.
So dealers are not really flashing the ECU with original software but with new software designed to prevent tunes? Is this right?
