Well, diesels are going to be loud. You aren't looking for loud, you are looking for a top end clatter.
Also, when you are as retarded as I think you are, you have to move the pump a /lot/ to get it to be noticeably better.
Try loosening all 8 lines on the IP, then loosening the IP and rotating it /all the way/ over towards the passenger side.
It'll be at like a 10-15 deg angle, and look really weird. Then, re-tighten the lines and see how she runs.
I wish I could give you a video of different timing sounds, but I can't right now.
