A P7100 is a P7100... Only major difference between industrial, Ag, and automotive are the governor assemblies, barrels & plungers, and delivery valves. Automotive P7100 make more power out of the box, but that will all depend on the pump number and application. And that is where the big debate of which is better.
As far as fuel plates we only use 3 options. 0 plate, no plate, or stock plate.
