VETERAN OWNED SINCE 2007

Meet Jesse

Jesse Tolley’s passion for performance runs deep — long before launching 412 Dyno Shop in 2007, he was chasing horsepower with his dad in a race car and tearing up motocross tracks. After spending a decade in the U.S. Navy working on complex weapons systems and teaching electrical and electronic troubleshooting, Jesse returned home to Tennessee with a strong technical foundation and a relentless drive to build something of his own.

Following his service, Jesse further sharpened his skills with welding and machine shop courses at TCAT and went on to attend numerous tuning schools, even stepping in as an assistant instructor along the way. Blending military-grade precision with a lifelong love of motorsports, he built 412 Dyno Shop into a trusted performance and repair destination for Decatur County and the Greater West Tennessee community.

Today, Jesse leads the shop with the same commitment he brought to every mission — delivering honest work, real results, and high-quality craftsmanship you can feel on the road.

Being new to Memphis, Tennessee, I faced challenges finding a trustworthy shop to work on my 2004 Twin Turbo Mustang. After receiving a recommendation for Jesse Tolley at 412 Dyno Shop, I couldn’t be happier with the experience. Jesse displayed true professionalism, even offering to pick up my car from two hours away (towing fee applied). He resolved every issue with the car and delivered exceptional customer service. For any future performance needs, I’ll definitely be returning to Jesse and his team at 412 Dyno Shop.
