D3 Performance Engineering is a new automotive shop that provides research and development, product design and manufacturing, engine management, and tuning. Although D3 has been in business for a little more than one year, it finally had its grand opening. D3’s team members are Evan Davis, David Donnals, and Chris Delgado. D3’s cleanliness exudes professionalism, and the custom fabrication work on many of its display cars is impressive.
