I use this, it comes with good regards on the diesel forums:

Lubricity formula, every fill up.
Not sure if this is just imagination but my truck stopped stumbling and quit it's black smoke puff after 4 hours of towing the boat. Higher duty cycle and a LOT of flow through the injectors may have helped.

Do you have a check engine light? You could have a cylinder contribution test performed, this would help with the diagnostics. I run TCW II two stroke oil in mine at 200:1 at the fifth tank full I run just Howes Fuel Treatment. It has been great and I am getting 16 mpg.

Stanadyne comes in at #8 in the Spicer Lubricity test. I use Opti-Lube XDI which is #2;

One more thing, check for water in the fuel. The owners manual explains how to purge it. There should be a light on the dash if you have water.

I found it on a Cummins forum(I own a 2006 Dodge dually). I notice more engine noise and clatter when I don't use the Opti-Lube so those who think the additives in the new ULSD fuel are enough might want to try one of the top five or eight in this test. Lots of guys don't know about this test so I like to post it when I can.
Here's the link to Opti-Lube;

Glowplugs-do yourself a favor and replace them all. wouldnt hurt to replace the relay also at the same time.
you can use 2cycle oil also for addative.. 1oz per gallon. my old 7.3 had over 210k on it when i sold it and the guy that bought it said he never drove a 7.3 that ran so good. The DP tuner chip helped some too.
