Is your fuel pressure up to par? I suggest you get a GOOD fuel pressure gauge with a longer hose, and drive around with the gauge, and see what the pressure is doing.
How about your exhaust manifolds? Have you pulled them off and thoroughly inspected them for cracks? Some are so small, a magnifying glass is needed to see them. Remember, these cracks expand as the manifolds warm up.

I have no idea. The easiest way is to go on a dyno with wideband O2, and log the whole band. Not a single gear pull. You need to show all shifts.
The other way is to buy a wideband O2 sensor and software ($300+), but that won't give you RPM data. Add a Gtech to the list, and if you're really creative, you can overlay the incompatible data from both units on each other for evaluation.
