'84 K30 Silverado "big Dooley"
It did pop like this last year but I chocked it up to the tune. I'm sure the old fuel is contributing to the issue as well
Factory filter use 9-10 micron factory rating . So if anything the 30 is letting in to much dirt .
I think the scale goes the opposite way doesn't it?
I think you're right but I still question the flow of my system. It does crank a while before starting sometimes
The number tells you the smallest piece the filler stops. So you want a small number because it stops small pieces.
i did some digging when i did my edelbrock efi swap and they required 10 micron filtration . i used a 90's caddy filter with 3/8" line size and clip on ends .
but if you look the filter up for say my 01 3500-HD truck with 8.1 it calls for this filter and shows 4 micron size filtration . https://www.wixfilters.com/Lookup/PartDetails.aspx?Part=160330 info on left scroll down to see micron specs .

I'm using a stock TBI filter on mine. Zero issues.
The lean under load *could be fuel starvation due to an overly restricted filter. But it could be a weak pump or regulator too. I'd get a fuel pressure gauge on it and see what's going on. Ideally a gauge with a long enough hose to pull it back to the windshield and watch as you drive. You want to see what it's doing under a load. Snapping the throttle in park with no load is not going to simulate the load going down the road.
With a baseline reading you can start eliminating the variables. Fuel filter, regulator or pump.
AutoZone has a fuel pressure test kit in their loaner tool program. Looks like it's got a long enough hose to reach to see it while driving.
Might be worth it to borrow the tool on a weekend you got free.

That's a good idea I'll see about renting a guage. I do have a new regulator but I hesitate to change it as my current reg is adjustable. The ep381 pump is supposed to be sufficient but I don't know if the tube adapter - 6an fittings are causing any issues or maybe just this China filter. I'll see if I can get some time to try this weekend
Haven't had the time to put the new fuel psi regulator in and test/adjust but I did take it for a short cruise.
Before I left I looked through the selections on the dakota dash and there's no signal for trans temp. This worked before.
Now I'm concerned that the new tcm being an 03 and the tcm is still a 01...
I don't know if this is the issue but I do know these things are almost year specific sometimes. Maybe I need to look for an 03 tcm.

Evidently my truck is burning down in my driveway as I type this. Just got the call from my wife. She can't put it out under the hood. I'm an hour away. The fire department is on the way...
WTF? No way
Wife said it's totalled. Entire interior all windows are gone
Probably mice
Major bummer!
Holy shit!
Not the update I was hoping for 
Gone.
Ahhhhhhh! That's horrible!
