i would also check ur ficm as well. jus cos it sounds like it's missing, it could be injectors or it may not. ur 1st indication is the SCT tuner. what tune do u have? if u got ur truck tuned, did u change out ur head studs and change ur headgasket as well?
sometimes a bad tune may be the cause of ur missing. did u take on a batch of bad fuel? bad fuel could be another cause. the six-o is very sensitive to stuff like tat. to check for bad fuel, drain ur HFCM. i recently took on b-20 biodiesel, she didnt like it.
i would drain and change out both fuel filters.
do u have an egr valve? if u do, have u popped it out to clean it yet?
btw, more info on ur truck and mods, and we'll be able to help u better. try going to our 6.0 forum. i'm usually there, and we have a tech folder with test procedures for no start or trouble starting.
some of the more senior guys to me are bismic, cheezit, blade35, mark kovalsky, piolet, amdriven2liv, mchan68, etc. all these guys are experts. they'll help u. we will all help u.
all the best!

Cold start miss
First thing I do is key on..wait till glow plug light is out, and fuel pump has stopped. Turn to start, and it seems like it turns over longer
Than usual before starting. About second gear you can feel a small miss that disappears after it warms up a little. Then no more
Problem rest of the day. No miss, and starts right up.
