Alpha Performance 2012 DSG S4: Stock ECU vs EPL Flash Back to Back

We took the Shop DSG S4 to the local dragstrip and ran it 100% stock, then flashed the ECU on site and ran it again — same day, same conditions, same driver. Our quickest stock pass was 13.03 @ 106.5 MPH. After the EPL tune was loaded the S4 dropped over a half second and picked up 4.5mph running a 12.45 ET with a best MPH of 111.01.
