The IA modified CIS fuel heads were modified by Larry Fletcher of Home - CIS Flowtech in Alabama.

It can be turned down by turning the six 3mm head spring tension adjusters under the six 4mm button head cover screws on the top of the fuel head counterclockwise a little while doing an injector flow test with all 6 injectors inside clean plastic water bottles or graduated cylinders.
Then some fine tuning of warm steady cruise and boost control pressure adjustments on an ajustable control pressure regulator/WUR.

It's best to send it to Larry and have him do it so it's done right the first time.
