I do not really care about dyno results. I care about how the car performs - power, drivability and use as a daily driver. With a Livernois tune alone - no bolt ons - my MKS went from 13.8 in the quarter when stock to 12.68 tuned, delivered better cruising fuel economy and was a much more enjoyable daily driver. I was tuned for over 40,000 miles with around 50 quarter mile passes and ZERO problems.
