Vacuum line unhooked or broken?

I'm with Mike. It's extremely unlikely that a new Injector pump would cause blowby. Has to be a hose or line left loose or unplugged. If you truely have blowby, then the engine is tired, and a new pump with as new pressures, just made it blatently obvious that the rings are gone.

I want a video of you looking at the blowby at 55mph+!!!!

That would be a trick.. Unless it's REALLY, REALLY BAD..

I won't go there I'm sure ISX would gladly mount his camera under the truck to show you that.

As for blow by typically it increase with boost pressure just the way things are. But I would say it going to be the vacuum lines are off first. If that all checks out then next step would be doing a compression test to verify the cylinder health.
