About Test Calibration

Test Calibration is a full sales and service company for diesel fuel injectors and turbochargers. We rebuild and calibrate diesel fuel injection pumps and injectors back to new OEM factory specs. We also sell new O.E.M. factory turbochargers (No core needed), fuel pumps and injectors. We also have re-manufactured exchange turbochargers in stock.

Test Calibration is located in Mobile, AL. Our primary objective is to always give excellent customer service along with competitive prices for the sales and service of turbochargers and fuel injectors. We opened our doors in 1976. Our primary mission at that time was to test, rebuild, service and sell diesel parts, fuel injection systems and turbochargers.  Since that time, the design and technology of injectors and turbochargers has changed. Today, manufacturers have advanced electronically controlled turbochargers and fuel injectors.  Test Calibration has a continuing education program to keep up with this advancing technology. We continually invest in some of the latest test and repair equipment. We also continue to stay up to date on the latest technologies available through continuing education. We do this so we can provide you with a full spectrum of services for these advanced electronically controlled diesel engines. Test Calibration can service and repair diesel equipment from just about any manufacturer. We also stock parts for many of those same manufacturers.
