On February 14th, 2014, we took our brand new Audi RS7 4.0 TFSI with only an APR ECU Upgrade to the track to see how it would preform. The vehicle was only fitted with our Stage I ECU Upgrade, 93 octane (Ron+Mon)/2, and the rest remained stock. The vehicle is fully loaded with the factory 21 inch wheels and tires.
We set a [email protected] MPH quarter mile pass after only a few attempts! The density altitude for the pass was between 160 and 135 feet above sea level at Montgomery Motorsports Park, an IHRA certified track. We continued testing and backed up the time with an additional thirteen 10 second quarter mile passes!
