Thinking further, is the mileage what the computer is recording, or what you are measuring at the pump when you fill up? Just wondering with all the work you have done to the fuel system if you have a leak somewhere? Possibly in-tank, if the small piece of hose has come off the pump pickup? There was photos of that on here a few months ago.
The low performance is one symptom of either reduced fuel flow or low fuel pressure, but you should not get poor mileage to go along with that. An external leak causing low fuel pressure on the other hand would cause that.

Is that your LTFT at idle? How does the STFT & LTFT look when driving around? Is it the same on both banks?
I haven't used the torque app before, so I am not too familiar with how it displays data. But you should be able to get readings for fuel trims on both bank 1 and bank 2 and voltage for all 4 O2 sensors. I have found the cheapy $100 harbor freight OBD scanner will give all this info in live mode.

I appreciate your input man. I just thought you were jumping down my throat a bit last time. Water under the bridge. Your insight and opinion are highly respected and appreciated.
Are the aftermarket rebuilt MAFsensors any good? I don't want another used one that can end up in a similar situation...
What about this one?

Most mechanics that I know don't know how to check the crankshaft damper. There are three ranges or rings on the damper. Put a white paint dot on each flange. Drive it. They must stay lined up after you stop. May take some driving. If they don't that could be the problem.
