Welcome to Master Tech Diesel Injection; Idaho’s Factory Authorized diesel fuel injection pump, injector, and turbo repair shop. We have factory training, tools, and test equipment to ensure proper performance of all our re-manufactured products. All of our injection pumps and injectors are bench tested and calibrated to factory specification. Every turbo charger we sell or rebuild is balanced providing long lasting performance. We can clean and test most gasoline and diesel injectors to verify if they perform to spec or if they need to be serviced or replaced. Our warehouse is stocked with performance products such as cold air intakes, exhaust kits, fuel filtration systems, brake pads/rotors, and much more.
