Proven Performance LLC is highly regarded for its reliable and honest diesel repair services. Customers appreciate their ability to diagnose and fix complex issues that other shops and dealerships often miss. For example, one customer’s GMC 1-ton dually truck, which kept blowing out the turbo tube, was successfully repaired after previous attempts failed. The shop’s team worked hard to fix the problem, and the truck now runs great, even under heavy loads. Travelers passing through the area also find Proven Performance helpful; they assisted a stranded diesel truck owner with diagnosis and advice, without charging for the effort, and suggested solutions that might be covered by factory warranty. The shop is known for quick service and thorough work, often fixing problems that other shops couldn’t identify or diagnose. Customers highlight the honesty of the staff, with prices that are competitive and transparent, sometimes even lower than online prices. One customer praised the team for fixing a year-long unresolved issue on their Ford F350 without unnecessary charges. The staff, including Brian, is described as professional, honest, and dedicated to quality work. Overall, Proven Performance LLC is considered the best shop in the area for diesel needs, consistently providing excellent service and earning high recommendations from satisfied customers.
Great work at a fair price. Thank you Randall and crew for your good work on my 99' F450.

The guys at Proven Performance are top notch. I was traveling and experienced some issues with my truck and they took me right in and got it fixed even though he was booked out with appointments . I can’t thank Randall enough and highly recommend this shop.
