No! They pump the same amount of oil no matter what injectors you have.
15* pumps can barely keep up with 160's, if you have 180 stage II's it'll be even worse

Well I would imagine that a weak pump sign would be inconsistent idling or rough idling and surging, but when you have 2's the engine falls on its face at high rpms, it runs out of oil on top end and throws a code till you restart

could a weak hpop cause the truck to surge and idle bad at start up and clear up a min or so after idling?
