Central Diesel, Betan Calibration and Denso Diesel Services Q.C. are three of the more known and better calibration facilities in town.

Calibration means that your fuel system, especially your injection pump, will be recalibrated back to factory specs. The procedure may also entail replacing/cleaning your injector nozzle tips.

Calibration is not a cheap procedure. Make sure your vehicle needs one before having it done. Don't overlook the basics like a clean air filter and fuel filter and that the inline fuel strainer screen on your fuel line is not blocked (I have yet to check mine :D whoops ).
