JBA Speed Shop and the Mustang Club of San Diego shook the block on Saturday during our dyno day. Over 13 cars ran on the rollers and put down some great power. We had everything from classic 'stangs to a brand new 2021 Mustang Mach 1. Thank you to everyone who came out and made the day a smashing success, and a special thank you to our tuner Bruce Tucker for putting in a marathon day.
