If the motors run the same, then they will trim the same as long as they use the same kind of fluid and there is no air in the system.

I've also heard of guys using some kind of resistor between the power lead and the ground of the fast pump.

Cool idea! where do I get one of these??? How much $$$? (or is this one of those "if you have to ask..." options?)
