I may have missed something, but it doesn't matter what chip you have now. If you change injectors, you will need new tunes.
I run FFD 250/100 injectors and I'm around 500hp or so on PMR's without issue. The tuner of choice will safely tune for pmr's so you don't do damage. I have ran several different tunes (PHP, Beans/no limit, powerstruck, etc) they all play nice with the pmr's. I just picked up a forged rod motor, but that is going in a project truck with a ZF6, so no reason to go full bore. If the forged rod motor was in front of my BTS, I could get a bit more and better tuning since there would be less worry.
238 or 250/100 would be a good choice if you want to max out what you have, but i would probably just do 238's. I think they tune better than the 250's. I have always had smoke while idling issues with my 250's, but it still passes emissions without issue.
If you want to spend money for injectors and supporting mods, you can do 238's or 250's. If you don't want to upgrade HPOP, etc, go with 160/30 or similar. I think 238's require upgraded fuel system as well.
EDIT: just went back and reread some things
there is a plug just behind the oil filter that requires a 5/16" square tool. I custom made one from square stock. There are plenty of youtube videos that show exactly what plug it is and what to look for. Basically if you see a nut, you have forged, if it's a bolt head you have PMR. My 01 manufactured in 00 has forged rods. all obs 7.3l have forged rods.
you need to set a solid goal for power wanted. if you do 238/250 100's no need for push rods/springs unless you are pushing over 40-45lbs of boost. if you run 200% nozzles you will want to do springs/rods. 250/200's will be in the 600hp range and you would want a borg warner S468 turbo with a Irate Diesel T4 mounting kit
for fuel upgrades, I use a strictly diesel kit on my dually, I went with an Irate kit for my new project. There are other good kits out there or you can build your own.
for clutch, you will probably want the south bend 650hp dual disc clutch, that is what was recommended to me. your 400hp clutch should hold up as long as you are easy on the truck. It will surely let you know otherwise.
