The injectors are HEUI and do not have an adjustment.

If you replaced them with new or REMAN or changed their location, the TRIM codes must be programmed into the ECM with CAT ET.

If you have adjusting screws, Valve bridges are set to .003 but, we just run the screw down until we feel it bump the stem and lock the jam nut.

Usually, they won't need adjusting but, if you moved the nut or screw, then they must be set.
