Power screw adjustment...

[Gary - K7GLD]

I've already adjusted my stock power screw to the maximum travel available with the limiting collar still attached - didn't actually get more than a quarter turn outta the adjustment before hitting the stop, back when I installed my banks stuff years ago.

NOW, I'm interested in additional adjustment for a little more power - but drawings and text on the subject are a bit vague as to exactly HOW to remove the collar to permit additional travel of the adjustment screw. Text with the photos indicate the screw/assembly should be removed carefully as to not lose the current adjustment positioning of the screw, and the collar removed - but are unclear as to exactly WHAT ALL it is that is to be removed? OR, how to remove it...

All I can see in the drawings, and in the limited view I can get on the pump itself on my truck, is the screw with collar attached, and the locking nut - is there something ELSE down there outta sight that must be loosened or unscrewed that permits the whole power screw assembly to removed as a unit?

AND, what seems to be the most commonly accepted amount of increase for lightly modded trucks like mine without objectional side effects - like vast smokescreens and poor fuel economy?
