Anything else while replacing injectors?

[BlkSC]

I have a bad injector so I decided to just replace them with 190cc injectors w/ 75% nozzles from Warren Diesel and I'll be putting an Airdog DF-165 on it while I'm at it. The oil cooler has been replaced, EGR deleted and head studs put in along with new heads from Ford. Is there anything else I should look into replacing or checking while I have the engine apart? Standpipes? Anything? Thanks!

Glow plugs wouldn't be a bad idea.

Glowplugs, standpipes and dummy plugs. Also the STC fitting upgrade wouldn't be a bad idea while it's apart.

Correct me if I'm wrong but I didn't think the '03's had dummy plugs and I thought it was after 2005 or so that they had issues with the STC fittings on the HPOP?

Doh!!! Didn't even look at the year of your truck.

hpop, icp or ipr sensors depending on how they are doing, or what your gauges say

What voltages should I be getting on the ICP and IPR sensors? Is there any way to check the HPOP without hooking up a gauge?

And when they did the studs, heads, EGR delete, and oil cooler, they also replaced the ICP sensor, oil cooler screen, MAP sensor, and oil pressure sending unit.
