Yeah,when things get too outa whack it's best to start over. Don't rely on someone else's data and tune for what your engine wants. Watch your duty cycle in the datalog. If DC is really high it's telling you that you need to turn the FP up. Like you said,one thing at a time.
Stock flow injectors? Go 14-15lbs. Why so much pressure? Why 89lbs/hr?
I don't think you're making enough HP to support that much fuel. Lots of headwork?
That's not a part I would used in the used condition. They're only good for about 60,000 miles.
Good O2's are $40-$70,I'm sure you've spent a hell of a lot more for your emulator.
Could be if you have leaned out the .bin. Normally the if the O2 goes bad it will go into open loop and run off the programmed AFR table. Look for O2 cross counts in your datalog.
Do you still have the stock unmodified .bin? For $hits & giggles drop that back in and see how it acts. Do a datalog and focus on TPS,MAP and O2. Look for any glitches in readings. Maybe even take the emulator out.
Have you tried to incorporate lean cruise into the .bin? Sounds like it's leaning out under mid MAP. I don't think it's pick up coil or you would be having misfires.
Yeah,we did that too. Once I found the area where the water was coming in I had him point a bright flashlight up in there. That's how I determined the size of the hole. Any plans of removing the dash? Save you having to stand on your head.
That's how I finally found my leak. Had my brother run a water hose all around the inside of the cowl while I laid in the floorboard and looked for where the water was coming in at. I turned out to be a gap they missed with the seam sealer big enough to poke a pencil through.
With the old non-roller chains it was more the chains wearing into the gears as it was the chain stretching. I once had a car come in where the chain was so loose it had worn through the timing cover. It's a little hard to judge chain stretch by watching the rotor button because of gear lash...
