I think it has more to do with the injection event than the number on the tach...

Whs! Injection system is the limiting factor here. That's why people have tried the mechanical injection route.

Nothing that I can change then? Tunes don’t do anything? I had higher rpms with Dyno proven tunes.

I'm sure there is a table in there somewhere. Need to look in the tuning thread for more detail on this. I'm sure Charles, HRT or someone touched on it.

but in a 7.3.... would you even go fast or use a calendar to see how fast you accelerate?
It might not be as fast as some on here but there isnt many other diesels around my home town or even around here that i know of that would spank my ass. Lol.. but again, id put it up against my 6.7....
