Car Tuning: Audi S7 Stage 1 by APR [VIDEO].

February 19, 2013 - The Alabama-based APR has released another teaser about its upcoming Stage 1 software for the Audi 4.0 TFSI. This past weekend the APR team took their Audi S7 development car to the local drag strip and nailed down some interesting results.

For comparison’s sake, the team ran stock mode as well. Even there, the S7 was exceedingly impressive with a 12.216 quarter mile at 112.42 mph. Running Stage 1 this dropped to 11.528 seconds and 116.95 mph. Then, running their 93 octane program they ran an even more impressive 11.634 seconds at 117.83 mph.
