Tunex Franchise

About Tunex

Tunex is a publicly held company (OTC BB-Symbol TNEX) that, through franchising, is engaged in the business of, diagnostic testing and evaluation of the performance of automotive engines and engine related systems, and all related inspections, services and repairs. Currently there are 29 company and franchisee-owned Tunex Service Centers in operation.

Founded originally in 1972 to provide an analysis of the performance of an automobile’s engine and related systems to inform the consumer of any existing conditions or problems, Tunex later expanded to perform the recommended service maintenance and repairs. The first Tunex Service Center began operations in Murray Utah in June, 1974. Tunex established a franchise headquarters along with training facilities and support services then sold its first franchise license in February, 1975.

Tunex completely "tunes" an engine, along with all under-the-hood systems, to new car performance in contrast to general automotive repair facilities or "quick tune" and maintenance service specialty shops. It is the Tunex "diagnostic first" method that separates this Company from its competition, together with solving the need or problem first, then pin-pointing potential problems rather than just performing tune-ups or maintenance procedures.

Tunex gives a written guarantee of satisfaction, and the guarantee is good at all Tunex centers no matter where the original work was performed. Tunex believes that the so called "tune up" will soon become a thing of the past. The only way to properly service automobile drivability problems is through diagnostic methods, carried out in spacious, modernly equipped service centers by skilled and specialized personnel.

Most services at Tunex centers are scheduled by appointment. A comfortable, clean and professional looking waiting room is provided for those customers who want to wait while the work is being done. All these Tunex services are available on a fleet basis to contractors and other businesses.


Tunex is the most experienced franchise operation in this specialized segment of the automotive aftermarket business. Though there are larger "tune-up", preventative maintenance and car-care chains and franchises throughout the United States, none are as specialized in their operating system and perform the services as extensively and as expertly as Tunex.

The primary objective of the Company is to establish a position as the most prominent automotive engine performance specialty service business in the country.
