It is called a compressor surge and bad ju-ju to the vanes of compressor/wheel if you surge it hard enough and a solid 1 piece part becomes a many piece part into the intake air tract the engine was not designed to nor likes to digest
Did you check alternator is it charging properly? how far gone were batts when replacing, bad batts kill alts, also look to last maintenance item, possibly did batt terminals loosen up since the batt swap,
were connections cleaned to bright shiney clean, and a corrosion inhibitor applied...
Another thought, if usings a factory style lift pump, trash in the outlet check of it could possibly let fuel drain back to the tank and maybe lose prime and your modified in tank pickup sucking air at low fuel level ?
Did you use a 6.5 sock with check valve in it or a gassser sock, it makes a difference, also does your former gasser tank have the baffle in it to keep from air being sucked into the fuel system in a turn with low level in tank sloshing over to one side?
Off top my head since we have cold snap on Gulf Coast rite now, you are having battery issues, I sent you a PM call me tomorrow clean terminals are a must, also the 2 positves left to right bank battery cable has a spacer connector between them that also has to be cleaned. if you have the...
Sealed system Al we get every bit as hot as you do in South Ms maybe even hotter at times and even towing to 18K I don't overheat, clean system, working fan clutch, stats and caps as designed are all that are required to keep the engine properly cooled.
Not ready to go there yet computers rarely go bad, you said new driver, new new or used but tested one, and new bought from where black or grey driver, mounted where ?

ko/ko for timing set is not same as ko/ko for theft learn timing is a minute or so, theft learn without scan tool takes about 45 minutes to complete and is a PITA
Yo Kev "pick up da phone man" reach out & touch someone did ya lose the # :)
KO/KO is as per Nobby's explanation, I'll add my experience also the hotter the better on coolant, I found out hard way if temp drops below 170F as seen by PCM/ECT not what your dash indicates there are (2) sensors...
So do 99% of the pictures of WWII workers that built the armaments that won a war, we could not even begin to attempt to fight a war today like that with current OSHA rules and ambulance chasers taking companies to court over "unsafe" working conditions, my #1 headache as a field engineer is...
Illville I moved your posts to their own thread it is easier to track a problem in it's own thread, once you find the codes post them your description is too broad to do much more than throw out a bunch of guesses.
When I had the Banks Stinger exhaust setup before going to my 4" Heath exhaust on truck now, the folks at Banks had a post turbo bung/locknut welded into the DP about 18" after the turbo in the straight leg of the DP, response for reading was not as fast as in my preturbo now but fast enough to...

Other consideration is charging rate/amperage for deep cycle batteries you can kill deep cycle batts with a chagrge rate being too fast, I run my camp on solar power using marine deep cycle batts AGM from a sailboat a buddy was parting out, and I "killed them" by using the wrong charger type...
PT what are you planning on doing with the truck that requires a fooler, can you update your signature line with current truck configuration, depending where you are in your setup a fooler may be premature just yet. Do you have gauges yet EGT & Boost at a minimum ? are my personal best...
Something not quite rite what psi you running on it, I'm 10-12 psi with my FRB-5 Walbro, what O-ring rubber you using, ? possibly wrong composition and the Diesel fuel is making it soft & skwishy and prematurely failing/leaking?
