first off ditch the muffler, chambered mufflers are no good on turbo diesels, if you really want a muffler get a straight through, after that injectors a fuel pin and a intake would be the next step, is it an auto or a 5spd by the way welcome to the site

You don't need injectors for the non-intercooled motor. Nor do you need the fuel pin right off the bat. Turn the full-load fuel screw in 1-2 turns, and bump the timing an 1/8". This is a better place to start.

If you wanted to know, what to do, when to do it, and how you need to go to http://dieseltruckresource.com/

Its strictily a cummins site.

Gauges Gauges Gauges!!!! this is what I tell everyone, especially with a non intercooled motor. Get your self a pyrometer and a boost gauge. I don't know too much about the first gen but I'm pretty sure it doesn't have a tach. If it doesn't, get one, I've heard some stories of people having the motor run away on them when trying to adjust the pump. Other than that, these guys are leading you down the right path. Oh yeah, maybe a smaller exhaust housing on your turbo.
And welcome to the site

Ah, how quickly we forget the simple things like gauges!
