John Ethell started JETT Tuning to fill what he saw as a void in the retail industry. After listening to all the stories going around in town and at the local tracks John realized that with his 15+ years in the racing industry that he could provide a better service, better quality, and a path to educate and inform the consumer. The products that are available as well as some of the inside scoop on what the racers and the racing community are all about. Photo: John Ethell learning from the master, late Merlyn Plumlee.
