John Thielen

John might be a recent addition to the Bullet team, but he’s no stranger to automotive and diesel. As a little kid, he was gifted at taking things apart and putting them back together (just ask his folks), and that naturally led to rebuilding his first truck–a 1984 Ford F250 6.9 IDI–as a teenager. Though he doesn’t still have that, he’s currently working on a 2014 F250 6.7 with the goal of pushing a cool 700 horsepower out of it… nothing crazy.

John’s had experience on both the automotive side with a well-known national chain and a dealership; and the diesel side with a smaller shop. He’s had factory training and a lot of on-the-job training, from standard gassers to heavy line performance diesel builds, high horsepower engines (see above), and custom turbo kits. 

He chose automotive and diesel because, like us, he had a passion for restoring trust in the industry. He chose Bullet because he liked the family atmosphere and our common belief that folks should be treated with kindness and respect.

He’s a family man, with a wife and one very energetic kiddo. When he’s not at the shop, he enjoys building RC crawlers and short course trucks, 4-wheeling with his Toyota and his Jeep (he’s speaking your language, a whole bunch of y’all!), hunting and shooting, and camping with his family and friends. 

He’d like to buy a big chunk of land in Wyoming someday (we agree!), but until then he’s enjoying hanging around with us and providing you with great service. If you’re having work done at the Jessup location, odds are you’ll run into him. Chat him up about your diesel perfomance needs. He’s got the answers!
