Engine woes or fueling issues?

Yes we have 10% everywhere where I live. There is only one ethanol free station within 30 miles of me and it has only 87 octane.
Also I don't live in the hood but basically every gas station near me is in the hood. They do weird stuff over there...
Do you mean checking for an intake/exhaust leak? To answer that no I have not. I can buy a smoke machine though.
Also where in the log do you see it adding fuel? To my untrained eye it didn't seem like it was based on the AFR.

Your 02 Sensor feedback and fuel trims Indicate it. https://trade.mechanic.com.au/news/u...rm-fuel-trims1

Remember when I said I was retarded? Yeah I was looking at the wrong channels for the fuel trims. Thanks brick.
Will get a smoke machine on order then. Ordered, says it arrives Saturday. We'll see about that.

For fun here is one with the MAF unplugged. Still had a hard start and some smoke coming out but not a lot. About 3 minutes and 30 seconds into the file, 7:33:50, I plug the MAF back in and you can see the change, I don't really think it is the MAF based on this information. Truck changed idle slightly but nothing drastic and no more smoke than with the MAF unplugged. If someone sees something I do not please let me know but I think it is safe to cross out the MAF in this scenario. Still dumping fuel like a mother though.
EDIT VERY IMPORTANT: Actually something I noticed that it did not do was dip down in idle and stall and surge like it was doing. I forgot this when I was typing, does that mean it is in fact the MAF sensor? Still seems to be dumping fuel but why won't the truck start first crank? Unsure.
Thoughts peanut gallery? I'm back to thinking maybe I need to just drive real rich until it decides it wants to give me a code lol
