I'm down on power. I've lost 5mph at the end of the my favorite race track's front straight. It's a 2013 Audi S4 with an APR ECU tune. Data dumps show that I'm consistently not accelerating quite as fast as last year, despite comparable or better exit speeds onto the straight. I'm a second off my best times. Weather conditions are comparable. Set up is identical. The car is well maintained but has 61,000 miles, 2000 of which are track miles.
