How does one verify if there is a tune on their car? I recently picked up a B6 S4 Avant on which has a JHM exhaust, Bilstein coilovers and brakes. My suspicion of a tune arises from the torque and acceleration especially in sport mode. My first B6 I owned 16 years ago did not feel as powerful (I know memories sometime fade). I there a way to verify either via Ross Tech VAG Com or otherwise if the ECU was flashed? TIA
