I am looking for some help (advice) finding a local (30-50 miles) reliable diesel performance\repair shop. Mostly for diagnostics to make sure my truck's (2000 Excursion 7.3) sensors, components, etc are functioning properly. I live in South Jersey about ten miles outside Philadelphia Pa. I sure would appreciate any tips or help locating a place where they are interested in performance diesels with a better knowledge base and customer service than the regular dealership.
