Marty's Diesel Performance is a business highly praised for its exceptional customer service and quality products, particularly its electric fuel conversion kits for 7.3L and other diesel engines. Reviews consistently highlight that the owner and staff are extremely responsive, helpful, and treat customers very well, providing support anytime, even on weekends. They gladly assist with troubleshooting and fixing issues, regardless of who originally purchased the product, sometimes at no cost. The well-put-together, simple-to-install efuel kits are noted for their installation videos, replacement part availability, and a spare parts bag included for resolving installer errors. Customers appreciate the option to choose specific parts for custom installs rather than buying a whole kit. The business is described as knowledgeable, professional, and a pleasure to deal with, often resolving problems when other shops could not. Many customers state they will not take their trucks anywhere else and highly recommend Marty's Diesel Performance as the first and go-to supplier for diesel performance parts and service.
Great communication, quick to answer questions and provide parts.

Really appreciated Manny and Jason. Did a diag on my ford 6.4. They were super honest and informative. I know they don’t make a living doing diags only but advised me not to do the work. Explained everything; highly recommend.
