Heinz Gietz Motorsports is proud to announce that William Knose has taken on the role as Master Calibrator in the Sorrento Valley performance facility located in San Diego, CA.

William is a second generation computer science engineer, after his mother an aerospace and computer engineer and a second generation tuner after his father who calibrated jet engines, based on EPA guidelines for fuel economy and maximum thrust levels.

William has attained a Bachelor’s degree from Saint Michaels College and graduated in 1999 with a major in Computer Science and a minor in Mathematics. In the time William graduated, he started tuning Subaru’s as one of the very first OEM custom Subaru tuners in North America. During his 13 years of tuning experience he has been involved in customizing the engine management systems in some of the most famous and well recognized vehicles of the past decade including the infamous Ken Block Gymkhana 1 and Gymkhana 2 race cars, Stephan Verdiers Formula Drift and Rally Cross race cars, Zenkai Motorsports Time Attack and Pikes Peak race cars, and the Crawford Performance’s Time Attack race car. His experience doesn’t stop there, he has also developed and received incredible feedback on his track tunes from the likes of Tanner Foust, Keiichi Tsuchiya and Tarzan Yamada, while applying that knowledge onto the tuned ECU’s of Dave Mirra, Travis Pastrana and Andre Lotterer (Two Time 24hr Lemans Winner).

Beyond the race cars and drivers he has worked with, William has also tuned hundreds if not thousands of daily driven and track enthusiast vehicles over his career. Not only has he tuned vehicles in North America but remotely (via the internet) around the world. William said, “Leading the engine management tuning department at HG Performance is a great honor from such a well-respected company and I am excited to be part of a legacy in the HG Performance brand, that is well situated in the European segment. I am even more excited to work with some great customers and exciting new vehicles.”
