Dr. Performance has been a staple in the diesel industry for 15+ years.  Originally started as a company featuring products designed for Cummins owners looking to get a little (or a lot) more torque for pulling their loads and getting a little more fuel economy to boot, their staple products were their line of "Twister" series performance upgrades, typically using injectors as well as turbo modifications.  Over the years, the company evolved into the racing atmosphere, even building a Pikes Peak hill climber dually!  Now, the company is still bedded deep in its roots of "more pulling power" through their line of performance chips, but now have moved even further into the racing segment, featuring such products as block girdles, billet tappet covers, starting line staging limiter, and so much more!  Truly this is a company that really got the diesel performance industry heading in the right direction for many others to follow.
