When I said we ran the pump on the stand at 2000rpm I meant engine rpm, so pump speed actually 1000. I went to swap governor springs yesterday and noticed one side of the governor is damaged and the stud the springs go over is bent a bit. I am pulling the pump off and bringing it back to the pump shop to sort this out. This time we are going to gut a set of injectors and set the breakaway on the governor at 5000 engine rpm. With the reduced load the stand will be able to turn that speed no problem. Thanks again for the helpful suggestions. This is a fun hobby for me and I enjoy figuring out how it all works just as much as the racing. Thats why I didnt just send it off and have a pump guy work their "secret magic".
When your truck was falling on its face after 2500, was the pump still fueling hard or did it clean up? It sounds like I need to take a good look at the governor on my pump.
