DiabloSport Tuners

At DiabloSport, we do not wait for others to develop the leading edge technologies needed to succeed we create them ourselves to gain the competitive advantages that help differentiate us from the competition. In fact we employ degreed individuals in various disciplines. These DiabloSport tuners and engineers are at the very forefront of developing breakthrough technologies for the 21st Century.

Our production follows ISO 9000 guidelines when assembling all components. All of our products are pre-assembled by our Surface Mount Assembly line, which includes critical devices like pick-and-place machines and de-stackers. Though automation allows us to be more proficient at assembling, the true skills are in the handwork of our employees. Soldering key components is a job best done by highly qualified individuals and at DiabloSport we feel that individuals are our best asset.

Quality inspection is a job shared by both person and machine. Key connection spots are checked via laser guided cameras to ensure proper conductivity. The integrity of EVERY unit found in our products is checked by quality control inspectors, we dont sample one or two per batch here. Bench testing isn't enough either. New tunes are tested in the field by authorized DiabloSport beta testers and changes for increased power or adjustability are instantly released in downloadable updates via our website.

Contact Southeast Performance for all product, application and pricing.
