I’ve been servicing my 2022 F-350 Super Duty at Jess Performance for over a year, and I’ve always been treated with professionalism and honesty. I currently have an SRT Jeep at the shop, and I’m eagerly looking forward to having it running at 100% after Jess Performance completes the repairs. Thank you, Jess Performance!

Best diesel shop in Michiana. Fair prices and excellent work on whatever type of diesel you have. It's not hard to see why they stay busy. They fixed my CP4 failure and installed a DCR conversion, truck runs like a top 40k+ miles later.
