This is a new calibration resistor for the pump mounted driver (PMD) on the 6.5L GM diesel injection pump. This sets the maximum fuel delivery volume of the fuel injection pump. This product slides right in to the connector of the PMD. #5 is the most common and #9 is the highest calibration resistor available, with the greatest increase in fuel delivery. This will give the vehicle a little extra power when at wide-open throttle. The difference in resistance level is often very minimal during normal use. This will become more apparent with greater loads on your vehicle, such as towing or steep inclines.
