When I traded in my 2000 A6 the dealership wanted me to include the stock ECU. So i've got my Revo Stage1 Programed ECU for sale. when I first installed this ECU my performance went way up. My fuel milage suffered a little bit but the difference in acceleration was huge. I remember the programer telling me that this added 5 PSI over stock.

Heres the number on the ECU

4B0 907 551 L

I paid 700 so i'm only asking 550 OBO
