Dobeck Performance develops and markets performance-related electronic fuel control devices to the power-sports and auto markets. With the complexity of factory OEM fuel injection systems, Dobeck Performance felt that it was important to give the motorsports owner/tuner a product that was easy to operate and understand, while not upsetting the stock fuel curve or any of its functions. The TFi is just that product. By attaching itself to the injector trigger wires and controlling fuel delivery as the signal travels to each injector, the TFi box allows all the stock sensors and inputs to function just as the factory designed. The company was founded by Mark Dobeck, an industry visionary, leader, and founder of Dynojet Research, the maker of inertial dynamometers, carburetor jetting kits, and early EFI controllers.
